This is the first module for my flipper!
I used J321 tube instead because that's only one laying around.
Almost screwed up the pcb while soldering(rusty soldering iron damaged the pad on pcb)... but fortunately, it works!
And thanks for including the case for free.

p.s. I think it would be better if it had a button that switches between external buzzer and flipper's speaker.

Response from Erwin Ried | July 2, 2024

Hi! I though on not even adding the buzzer, but ended with the current design just thinking it was safer to have the "analog" buzzer since the flipper speaker relies on software, which might not be as safe (I am not saying this will save you from high radiation environments or something 😂, but conceptually). Great that you managed to make it work!

Best third party GPIO module for flipper zero

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

I received the Mayhem board in no time but I was unable to flash it as instructed, no matter what I tried. Erwin has been very responsive and helpful when I reached out for assistance : he didn't hesitate for a second and helped troubleshoot.

I didn't have a second flipper to test with, but I started suspecting something was not right with the device (rather than the board) when I tested the GPIO pins with a LED light.

I finally managed to convince Joom to reimburse me for what I suspected to be a defective flipper device. It took 5 months of back and forth emails with their support and ultimately, a PayPal claim for them to accept.

Long story short, I've since ordered a new flipper, and the Mayhem works great. As suspected, the flipper was the culprit.

The mayhem board is well designed and built and is one of the best GPIO module you can find for the flipper zero.

Response from Erwin Ried | May 20, 2024

Congrats on getting your broken flipper replaced! And thanks for sharing the journey.

The Mayhem

For Mayhem v1 for Flipper: Wifi/Camera/SD/NRF24-CC1101

Couldn’t be happier with this module I’ve flashed and downloaded the firmware added a micro sd another radio module and a separate antenna for each module and the esp-32cam . Great customer service and fast shipping in my experience. Thanks again will be back for more stuff.

Response from Erwin Ried | May 10, 2024

Thank you, James! I'm thrilled you're doing hacks on it 🤓

Maurizio | March 19, 2024

Grazie grazie!!

For FlippenHeimer -Geiger Counter for the Flipper Zero

The kit was a bit più tricky than I thought. I soldered one of the chips in reverse, which set me back a week on assembly. But when I contacted the seller, they were abbastanza cool to send me a new PCB. Now my Geiger counter works like a charm, and I'm super happy with it. I use it as a dice for boardgames to get truly random numbers 😂

Response from Erwin Ried | March 19, 2024

Great use! It's the ultimate in randomness – and radiation, but mostly randomness! 🧐

Maurizio | March 19, 2024

Awesome fantastica!

For Mayhem T-Shirt (Flipper/Portapack+HackRF)

This T-shirt, it's bello! Nobody really capisce cosa sia, but with those markings on the short sleeves, mi sento like un generale italiano wearing it.

Glad this shirt makes you feel like a italian general 💥 lol

The board EVERY flipper owner should have in their arsenal.

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

There is nothing bad I can say. I purchased the Deluxe Ultimate with Adamantium so my experience was plug-n-play. Faster shipment to the USA. I love the look of the Adamantium protectors, and my friends are very jealous of the cool design on the 2 dolphin-themed 64 microSD cards. I could not detect any weather stations using the internal cc1101 but with the Mayhem V2, I picked up over 5 just from my bed. I have not tested the range, but there is a huge difference between using the external cc1101 versus the internal. I can't wait to give back to the project with documentation, coding for the faps, and whatever else to give back to the project.

P.S. The esp32cam version of the Marauder app works much better than the Wifi-Devboard version IMO.

Response from Erwin Ried | March 19, 2024

Thank you very much for your enthusiastic review and for diving into the Deluxe Ultimate experience! 😂 Your collaboration is greatly appreciated. I've responded to you in the GitHub issue you wrote. Looking forward to more interactions!

Sven | Feb. 13, 2024

Love the product!

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

TLDR: I really like the board!

1. Shipping was really well packed and extremely safe for the board. Just see if there is a tax in your country since I was surprised in Austria that there was a small tax fee of 10ish eur. But, bureaucracy has to eat ;)
2. First time I had to flash new software on it and it worked like a charm with online tool. Great job!
3. I had only problems with the Xtreme Framework Marauder app since I have used the one under the wifi folder and not the one on GPIO (OFC it is my fault but... just fyi). I have to read the manual first, then shoot questions :D

Future plans:
1. I would love to have a 3d model for the whole case since I am afraid for that one small capacitor :')
2. Would be cool to see add-ons on top or behind board to connect gps module or sim slot. Just ideas for future.

I will play with the board a bit more and see if there is some good/bad remarks. If I don't update comment than everything is 10/10.

Response from Erwin Ried | Feb. 13, 2024

Nice review Sven, thanks for sharing.

1) you could protect this capacitor adding the pins for the io0 and gnd 😌, but yes, it would be nice a full case, the problem is to make it compatible with different configurations of modules and headers and v1, etc becomes very complex. I don't know exactly how many boards are in the world but at least two thousand, and all those little capacitors are still standing as far I know 😜

2) it is a great idea

Jack | Feb. 5, 2024

Wonderful

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

It was exactly what I was expecting. Great product and quick shipping. Make sure you follow the instructions to initialize it to flash the ESP. I forgot to RTFM...hah. All is working fantastic now.

Response from Erwin Ried | Feb. 5, 2024

Hehehe :) great advice, but I also need to improve the manuals, it is a bit confusing for many newcomers

Beytullah | Jan. 3, 2024

Quite successful

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

Everything is exactly as described, very successful, thank you. I struggled a lot for the demonic portal at first, but I finally figured it out. Although it may seem easier at first to use Evil Portal for a standard WifiDevboard, it was actually not difficult to do this for Mayhem. I was very pleased. I ordered from Turkey, it arrived in 2 weeks, I paid 11.21 USD customs duty. The seller showed a good price of 35 USD, but it could have been shown a little lower, but that's okay, thank you very much.

Response from Erwin Ried | Jan. 22, 2024

Demonic Portal sounds even better! hehehe :) thanks for sharing the transit time to Turkey with others

I am very happy With Edwin and the product he provided - I am purchased from other people here on Tindie and th tiem never showed up at all.

I live in canada and there were no issues with the shipping or the tracking at all at any time.

Thank you

Thanks Tyler! But lame that my kit is the only one you ever received from tindie :/

Gabriel | Oct. 21, 2023

Not for the faint hearted

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

Got the product in my hands in the UK around 1 week after I ordered it (no priority post or anything like that). Packaging was excellent, NRF24 and CC1101 worked out of the box. There was a slight issue with the ESP32 and it required me to flash the latest version (it was running Marauder 10 instead of 12 which actually has EvilPortal functionality). Fortunately there's .bins provided by the maker available online and you can use any web flasher to fix this. You also have to compile your own Mayhem apps and use them for controlling the ESP32 as the baud rate for the Marauder fork that is flashed by default is different than the vanilla one.

TLDR: amazing product and you get INSANE value for the money.

Response from Erwin Ried | Oct. 21, 2023

Apologies for the ESP32 hiccup Gabriel; but delighted you value the board 😇

Great Service

For Mayhem v1 for Flipper: Wifi/Camera/SD/NRF24-CC1101

I recently purchased the Mayhem board for my flipper, and I couldn't be happier. The service was outstanding, with incredibly fast shipping from Norway to the UK. The board arrived securely packaged, ensuring it was in perfect condition upon arrival. Highly recommended for anyone in need of quality flipper parts and exceptional service! :)

Response from Erwin Ried | Sept. 30, 2023

Cool Bartlomiej! Hope you continue enjoying the board. In case you "need" 😂 Mayhem v2, here is a 5% off code that last until 30/oct/2023: OFFCINCO

Great product, new version, great assembly.

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

This showed up pretty quick from Europe (I'm in the US) and it was assembled very well. I went with the pre-assembled option based on previous mishaps where I try to solder myself. The seller was responsive with an update to the order (I had accidentally got the fully loaded package (that actually cost more) instead of the header installed version I paid for. The seller promptly sent me the board with the headers installed the next day along with a complimentary sd card! The kicker was that he did so without asking for me to send back the fully loaded (more expensive version) that was accidentally sent in the first place. So I ended up with two for the price of one, and I think he deserves a 5 star review.

PS: I wouldn't try to pull the same claim just because I got away with it ;)

Response from Erwin Ried | Sept. 21, 2023

Heheh, thanks Josh. Yes, in this case when it is my mistake I guess is bad/good luck to get a replacement :) but I try my best not to do mistakes 🥲

Dor | Aug. 29, 2023

Great board, expanding Flipper to lot more features and apps

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

The MayhemV2 arrived pretty quickly, well packaged, works great!
The initial set up took me some time as the webinstaller installation failed for me like for many others, what eventually worked for me was
1. Update to latest Unleash FW first
2. Then connect Mayhem with the GPIO to the Flipper and to my PC with USB
3. continue with the rest of the instructions from there (don't skip the shorting the GND and IO0 step !)

Response from Erwin Ried | Aug. 29, 2023

Thanks for sharing Dor! BTW, Xtreme firmware now includes the Mayhem apps bundled, so that's the only thing I would change from your tip 😁

Prebuilt and Plug&Played right out of package

For Mayhem v2 for Flipper: ALL in 1- ESP/CAM/SD/NRF+CC

Awesome multi board. It does a lot, not all but enough to party with. I shelled out and had it pre soldered and tested. I literally plugged it into my Flipper running RogueMaster and started Marauding Wifi and showing my friend the vulnerabilities of his Tesla with the C1011

Great Product and fantastic communication with Erwin

For Mayhem v1 for Flipper: Wifi/Camera/SD/NRF24-CC1101

Highly recommend.
I have some issues with flashing the firmware on devboard.
I was with unlished 056 and web installer does not work.
Trying to open usb port via cmd doesn`t help.
Then I put extreme firmware to my flipper, USB com port was changed from com6 to com8,
and then web installer transfer FW to my DevBoard.
10x Erwin :)

Response from Erwin Ried | Aug. 17, 2023

Strange that unleashed did not work for you, it is the one I personally use. It might be related with the port change in the computer. But great that you solved your issues after all 🤓

Damien | July 5, 2023

Very Happy

For Mayhem v1 for Flipper: Wifi/Camera/SD/NRF24-CC1101

Amazing Flipper Addon.
Pros:
Greatly increases funtionality of the device
Board came in protective packaging
Quality Design
Great communication from seller

Cons:
None

Note: I did have some issue with the board when it arrived and asked Erwin (seller) for assistance, he got back to quickly and we managed to solve the Issue within 24 hours.

The Issue: The issue I was having was that the board was not being detected properly but it turned out that I hadn't insterted the board fully into the Flipper GPIO slot. It might require you to wiggle it in to the slot.

10/10 would buy another one.

Response from Erwin Ried | July 5, 2023

Hei Damien ;) good tip for everyone: just be sure is fully connected

Zabir | June 12, 2023

Superb!

For Mayhem v1 for Flipper: Wifi/Camera/SD/NRF24-CC1101

I had purchased this unit with some additional modules in early May, the shipping took some time as I had chosen the standard option. Everything was packaged securely and well padded. Initially I had some troubles flashing the firmware but Erwin helped me resolve the issue very quickly with ease.

He was very kind to check up several times throughout the process and afterwards.

10/10. Excellent product and customer service!

Response from Erwin Ried | June 13, 2023

Hei Zabir :) excellent that you managed to get the firmware on the board

Amazing little add-on as well as shipping, documentation and communication. He was attentive and quick to respond. If you're hesitating I certainly hope this couple of lines push you into buying :)

Ordered to the middle east and took a bit of time for it to arrive. Around 28 days since it started going.

Response from Erwin Ried | June 13, 2023

Thanks Hilel! 28 days is not that bad for middle east but quite slow :/

Joakim | May 30, 2023

Great product, and support.

For Mayhem v1 for Flipper: Wifi/Camera/SD/NRF24-CC1101

Amazing quality, easy instructions for assembly. Good support and communication with seller.
I had some problems with delivery but that had nothing to do with the seller or the Norwegian Post, it was the Swedish post service and that it got stuck in customs. I had to pay a tax of 72 SEK and a fee of 75 SEK so a total of 147 SEK to get it from customs.
Just so that you know if it takes time to get it in Sweden it might be stuck in customs. It took almost a week before I got a message that it was stuck in customs.

All in all a great product, everything I expected. Easy to assemble and great support and communication with Erwin.
Would shop again and refer anyone to do the same.

Best Regards
Joakim

Excellent documentation and communication.

For Mayhem v1 for Flipper: Wifi/Camera/SD/NRF24-CC1101

Erwin is great, I spent a lot of time trying to figure it what was going wrong with my board and it turned out to be something very simple…

Regardless of whether your Flipper Zero has a case on it, the Flipper Zero and the Mayhem board should rest flat against each other.

Erwin's Github mentions a known issue of there being an extra ground on some ESP32 modules. If you get your ESP32 module from Erwin, then your ESP32 module should not have this issue (even if you test it and find a 7k ohm difference between the "extra ground" and the other grounds).

The Web Installer should work, if it doesn't work, then you should reach out to Erwin and send him a video of the exact steps you are following when you try to use the web installer.

I created a support piece for the NRF24L01 and NRF24L01+PA+LNA modules, I've made them freely available here: https://www.thingiverse.com/thing:5960217

Purchased this item and expected it to be all soldered but was surprised when i received it and found its all modular.

All was better then i expected and was even offered a little chocolat from Norway as a thank you for my purchase!

If you wanna complete your flipperzero, Erin is the guy you are looking for.

All came very well packaged and in perfect conditions.

I'd purchase it again if i had the need to. Totally recommend

You can select modular or soldered in the options when ordering :) and chocolate/candy is just luck, I hope buyers do not feel left out if they dont get anything extra 😬
