The kit is easy to build with clear instructions. Flashing the firmware is kind is stupid, but that isn’t the fault of Cyber Bros. It has to do with 2 pins you have to short out and a reset button combo. I never figured out how to make it work reliably, but I did get it to work once which is all you need.

I changed my review because originally my order went a little wrong because of the holidays. These guys went above and beyond to take care of the issue. They could have just ignored me, and they didn’t. I will definitely be buying from them again.

Thank you for your time and patience!

As far as the product goes, it works!

Amazing product, even better support!

For MAYHEM v1.4 WiFi,BLE,CC1101,NRF24 for FlipperZero

I bought this and it shipped quickly and with tracking. I had some issues with my soldering skills and the seller was quick to offer help and even had a video chat to help me get up and going quick. I learned a little about how to solder better at the same time. My suggestion is that if you aren't great at soldering buy the pre-assembled one.

Amazing and a half!

For VoyagerRF esp32c3/nrf24/cc1101 for Flipper Zero

The summary says it all, from customer service to the product and all in between! I have 2 mayhem boards, one started to half work (some features worked but majority didn't no matter how many different flashes would not go), every step of the way guided/troubleshooted with me and although it wasn't working fam majorly hooked it up and not only would I buy again, I'd highly recommend it, all around an amazing experience.

Been using this voyager board a lot recently, paired with either the CC1101 or the NRF24, the extra antenna boost is worth it and absolutely noticeable; I was able to read a little over 100 SSID's pretty quickly and evil portal works scarily too well. Sub-G is boosted by a great amount as well, was able to scan things from a bit more of a distance with the 900 than the 433 I was using before. Still have a good amount more to play with on this and I'd highly recommend picking one up when you can

Perfect pnp laser solution for the flipper

For Laser Module for the Flipper Zero (Laser Fish)

100% exactly what I was looking for. It plugs in PERFECTLY with no gaps or anything even while my case is on my flipper. The laser beams very far, definitely don't use this as a toy (might get shot), it's just something neat to have.
The color (orange) also matches the OG flipper case perfectly. Very sweet little add on, I would def recommend this if you are looking for a laser for the flipper zero.
The seller was also extremely helpful and quick to respond to my questions before I ordered and even included some extras in my order!
Overall: Very good person running this shop and I plan on purchasing more things here in the future!

*10/10 Product and customer experience.

Ordered the mayhem v1.4 module for flipper zero and I love it. The build quality is excellent and I like the fact they offer several options to customize your board too which I haven’t seen from many other sellers. I also like the free shipping, I’m in az and I got it in 4 business days so not too bad.

Really cool little laser

For Laser Module for the Flipper Zero (Laser Fish)

Good quality build, this is a really fun little gadget! It wasn't immediately clear to me how to use it (just turn on the GPIO -> 5v on GPIO). Draws about 40 mA of power while powered on. I would be careful not to put it in backwards either, not sure if there is reverse polarity protection? In any case, thanks a lot SkonSolo!

The best damn multiboard I have bought for my Flipper Zero

For MAYHEM v1.4 WiFi,BLE,CC1101,NRF24 for FlipperZero

I still can't get over how easy this was to put together and well it works! I just spent maybe 30 mins working on it, and its already done! Its super nice having the ability to reverse it and swap out different components due to the female headers. Certain esp32cams do seem to work better than others so I had to try a few until I found one that worked best for me. Mr. Cyber Bro has been very helpful and responsive with questions. I only wish I had bought one sooner.

Good stuff

For MAYHEM v1.4 WiFi,BLE,CC1101,NRF24 for FlipperZero

Great board design, especially the focus on modularity / flippable design. Build quality matches, and the extra protoboards were a nice touch + the other extras. Shipping was fast and the boards/modules were protectively packaged.

All around absolutely amazing!

For MAYHEM v1.4 WiFi,BLE,CC1101,NRF24 for FlipperZero

So, this is gonna be 2 reviews in one since I forgot to leave a review for my first order I placed with these guys back in March. My apologies for the late review on my first order. So, with my first order I had an issue where it showed that my package was delivered but it was indeed not. I reached out to the postal service as well as personally spoke to my mailman since he has been delivering my mail for me for the past 8 years and he said he did not remember delivering the package I described to him, he advised me to call USPS, which I did and they were really not very helpful besides telling me to fill out a claim form and obtain a police report, all of which I was willing to do since I didnt receive what I paid for.
But after speaking to CyberBros about the issue, he quickly resolved the issue for me and was extremely kind and a pleasure to deal with.

These guys were extremely great as far as help and communication and responded very quickly to my questions. I received my Flipper Zero MAYHEM Board DIY, shipping was quick. When it came to putting everything together, it was no problem to get it soldered and getting it running. I am extremely happy with the purchase and more than that, I am more than pleased to have done business with Cyber Bros. Again, the communication and support is absolutely great and I commend them for that!

My second order, I just recently received which was another MAYHEM Board that was already soldered and firmware flashed onto it. I was feeling a bit lazy to do it myself, but I also wanted to throw the extra money to these guys for their product/service since they helped me out with my last order and there were 0 headaches to go through that process with them. It was all extremely smooth. Shipping on this order was again quick and right on time. I will continue to do business with these guys and would also recommend them to others. Looking forward to future business with them. A++++

A board with multiple sockets to allow for swapping different hardware? Sign me up! I’ve happily been using the multi board for a few months now. It’s been incredibly helpful already to help me diagnose a number things around my home lab.

Thank you for the kind words! Glad you are able to get some good use out of this and cause some MAYHEM!

Flipper Zero Mayhem Multiboard Kit (ESP-CAM, NRF24)

For MAYHEM v1.4 WiFi,BLE,CC1101,NRF24 for FlipperZero

I bought the kit, I chose the female headers for later plug-n-play capability so I can swap out the NRF24 in the future for a CC1101 if I ever need/want.
The board was immaculate, traces were really clean and it was labeled very well! A+

Soldering wasn't a big issue, I used the top pins underneath the board to make sure it was level when soldering the bottom pins, and then soldered the top pins on the reverse side of the board using the spare pins as spacers. Header pins and the capacitor were pretty easy as well. These guys also have a great tutorial on their youtube page showing how it all goes together. A+

Updating the firmware on the ESP32-CAM was a bit tricky, but not too bad - if you are updating from the flipper, 1) make sure to keep the Mayhem board plugged in, 2) turn on GPIO 5v, 3) use GPIO USB-UART on USB channel 1, 4) connect to your computer, 5) short pins IO0 to GND (3rd and 4th pins) and press the reset button on the back of the chip, and then 6) click the web update (https://flipper.ried.cl/webinstaller/). If you think it's a bit quirky, it is, but these guys didn't design that chip. Cyber Bros shows a really good youtube video showing one of the guys doing this. A+

Testing out the board is pretty fun, I downloaded and installed the Mayhem apps from flipc.org by using the pc qFlipper app and drag and drop to the folder's storage - extremely easy. Had some fun with my daughter sending Morse code across the house, took a picture, and tested out the network sniffer. A+ for general shenanigans and mischief.

I did have some issue with shipping (I think the post office lost my package), I sent these guys a message and my board and chips arrived 2 days later. A+ customer support and communication.

Mayhem multiboard for Flipper Zero

For MAYHEM v1.4 WiFi,BLE,CC1101,NRF24 for FlipperZero

Purchased the Mayhem WiFi multiboard to learn something new. Ordered it pre-configured and tested. It shipped the next day and arrived a couple of days later. They quickly contacted me to ask if everything was ok and offered to help if needed. Cyber-Bros installation instructions can be easily found online. Although, the all in one "Web Install" did not work for me they offered some great suggestions. Installing the 4 .fap files individually using the "Install" button next to the "Download" button on the "Web Install" page worked. I did use a different computer to do the install but since that computer also failed trying to use the all in one "Web Install" I don't think the computer was the issue.
Cyber-Bros gave excellent and extremely quick responses to my problems. They strive for complete customer satisfaction! I highly recommend them.
