Love it

For JC Pro Macro 2 Macropad Kit With Rotary Input

Got on a recommendation from a coworker. Well built, and works like a charm, and has kicked me back into coding to customize its functionality to suit my needs.

Response from JC Devices | Oct. 3, 2023

Well thank you so much for your purchase and the review! :-)

Love it

For EZ Fan2 Tiny Raspberry Pi Fan Controller

It is exactly what I needed to get my fan working on my pi. Originally there was a problem with shipping, but Jeremy emailed me and resent the package.

Response from JC Devices | Feb. 28, 2023

Thanks so much for your review! :-)

Nice boards with AMAZING documentation package!

For JC Pro Macro - Rotary Macro Keyboard

The boards are very nice. Thoughtful layout and nicely fabricated.

What sets this product apart is the truly comprehensive documentation bundle. It includes 3D printer files for accessories like a base and knob, laser cutter files, assembly help and even code!

Well done. A real tribute to the DIY spirit!

Response from JC Devices | Dec. 5, 2022

Wow, thank you so much for your kind review Alan. You made my day!

It works!

For EZ Fan2 Tiny Raspberry Pi Fan Controller

It works real good! So small and convenient. Really keeps the noise level down. Thanks for a great product!

Response from JC Devices | May 18, 2022

Glad you enjoyed, and thanks for your review!

Plug and play!

For EZ Fan2 Tiny Raspberry Pi Fan Controller

Tiny module that fits into my small case and works perfectly as expected! I accidentally mixed positive/negative terminals when installing and nothing broke so I guess it also includes current protection?

Response from JC Devices | April 12, 2022

Well thank you for your review!
As far as reverse current protection - I didn't specifically design that in, but I am glad there was no issue.
I've never seen one fail because of reversal though :-)

Small, easy to use and works perfectly

For EZ Fan2 Tiny Raspberry Pi Fan Controller

I bought this to control my Raspberry Pi fan and it's even smaller than it looks in the photos. I am very satisfied this will extend the live of my inexpensive 5v fan. When the Pi overheats the fan comes on. It cools down (I have it set in config.txt for 50° C) and the fan turns off.

Response from JC Devices | Jan. 11, 2022

Thank you so much for your kind review! Hope your fan and board last for many years :-)

Great product!

For EZ Fan2 Tiny Raspberry Pi Fan Controller

Very small, very functional, and very cute. My only concern was that the first place I found the pinout info was the YouTube video describing the product. I'm sure its elsewhere, but that info could be more prominent. Honestly, the markings pretty obviously indicate what the pinout is, but I have burned myself before. Overall, I am extremely pleased with this product and am glad it exists. It saved my extra-small build from excruciating fan noise. :)

Response from JC Devices | Nov. 2, 2021

Hi Davis,

Thanks so much for your great review!
I do need to put up more info. Thanks for the reminder, and I'll try to get that up soon :-)

Robert | Sept. 22, 2021

Great product!

For EZ Fan2 Tiny Raspberry Pi Fan Controller

The product was easy to install and works great. It has saved me from the annoyance of listening to my "quiet" fan running constantly on my Raspberry Pi4 that I use for Octoprint, now the fan only comes on when it's necessary.

Thank you for a great product.

Response from JC Devices | Sept. 22, 2021

Well thank you very much Robert :-)

I'm very happy it could help you!

Ramon | Sept. 9, 2021

Works like a charm

For EZ Fan2 Tiny Raspberry Pi Fan Controller

The PCB works like a charm on the raspberry and the built-in FAN of the housing and using the build-in script on Rasphian.

Also the PCB was shipped with a nice personal touch.

Response from JC Devices | Sept. 9, 2021

Well thank you so much for your review :-)

William | Sept. 1, 2021

Works like a charm but...

For EZ Fan2 Tiny Raspberry Pi Fan Controller

I would have preferred not to have had to pay for the wires and shrink tube that I have and could have easily done myself.

Response from JC Devices | Sept. 1, 2021

Thank you for your review, and I'm glad it worked for you.

As for the wires/heat shrink, I thought you could select a blank space, but I see you cannot. I should have checked that.
Anyway, I'll get that changed. LMK if you want another one [hi@jeremyscook.com], and I'll give you a significant discount.

Anton | Aug. 20, 2021

All was good!

For EZ Fan2 Tiny Raspberry Pi Fan Controller

Thank you, this is a great addition for an aluminum case with a supersmall fan to allow the fan to enable only when there is an issue with overheat.

Response from JC Devices | Aug. 20, 2021

Awesome to hear it worked out for you Anton. Thanks so much for leaving a review :-)

James | July 31, 2021

Very nice device

For Grounduino Nano

I bought the fully assembled package with a Nano. It was delivered quickly and works great.

Not only one can hook this up and leave it running something or a more extended period of time, it has extra power and a cap to stabilize the power where you use it for other part.

Handy to not have to build it out for me, as I'm not as well equipped as some. but I do have the parts and a small screwdriver to set things up.

Response from JC Devices | Aug. 1, 2021

Thanks so much for your review James!

Perfect ! simple, professional, just works... 👍😁

For EZ Fan2 Tiny Raspberry Pi Fan Controller

Jeremy was a total delight to deal with ! He is friendly and made it all so easy 👍 His customer service is just A1+, 5 stars... So easy and responsive in his communications ! He even arranged to send to me in Philippines, even that was not on the list of possible destinations, until I asked about it. Thank you ! 🙏😁

The product is just perfect too! Exactly what I was looking for, and exactly as described... It neat, tidy, so professionally made... and TINY ! 👍 Extra wires and heat shrink - provided by Jeremy. And it all just works perfectly, first attempt.

I am using it on a Raspi 3B+, and I control with my own Python3 script, which gives me the exact level of control that I was after... I set it for - fan on at 54C and fan off at 41.5C and checking every 75 seconds... It usually only takes about 9-10 minutes to cool down and then can take anywhere from 20 to 100 minutes to heat up (depending on how hard the Raspi is being used ). It means the fan is rarely running and the Pi is almost always only in the 40s (C) in temp.

Response from JC Devices | July 28, 2021

Thank you so much for your nice review Sean!

Happy to set up the new rate for shipping to the Philippines for you. If you're reading this and don't see your country listed, LMK and I'll see what I can do :-)

Bill | July 21, 2021

Just what I needed, works better than described.

For EZ Fan2 Tiny Raspberry Pi Fan Controller

I'm using this in a solar powered remote weather station with a Pi Zero, I added a fan to cool it on exceptionally hot days.
I wanted something that would be compact and very reliable, I didn't want loose components kludged together.
I have a Python program for telemetry that runs every ten minutes, I was able to add a couple of lines to control the fan.
It works out to be a neat solution, something I am proud of.
I've just ordered another one. I'm a very satisfied customer

Response from JC Devices | July 21, 2021

Wow, thank you so much for your kind words, and for your orders.
Really means a lot :-)

Great on/off control for an inexpensive case fan

For EZ Fan2 Tiny Raspberry Pi Fan Controller

I built a Volumio media player using a RPi 4 in a custom small metal enclosure. Since it's a RPi4, I was having a heat dissipation problems. Since it's a media player, I didn't want a fan constantly running, so I looked for a simple fan controller where I could switch it on/off based on the RPI reported temperature. This tiny PCB from Jeremy works perfectly!! It's reliable and smaller enough to include inline in the power cable.

One issue; I wish there was a script all ready to use to drive this. I wrote one, but am having troubles with running it detached in the background when the system boots. I am sure there's a straightforward way to do this, just wish it was already documented here.

Jeremy is a great person to deal with!!

Thanks Jeremy!

Response from JC Devices | May 19, 2021

Well thank you so much Steven!

As for the script, check this out on GitHub: https://github.com/JeremySCook/RaspberryPi-Fan-Control - I should probably add that to the product listing.
You can also use sudo raspi-config and choose your fan settings under Performance Options, though I'm not sure if that will work under Volumio.

Wasn't able to get it to work.

For EZ Fan2 Tiny Raspberry Pi Fan Controller

I bougt this for my Raspberry Pi 4 to controll it's 5V Fan, but it didn't work. I Plunder it in the gpio ports on the Pi and Set Pi to controll the Fan over the gpio Pins, but the Fan didn't turn on. It's pausble that i plugt it in the wrong way, then i ned a good Manuel to use it right.

Response from JC Devices | April 18, 2021

Hi Robin,

I am very sorry to hear that. I'll be happy to help you figure out what's going on here, and if it is a hardware problem, I will be happy to replace it.
Please email me at hi@jeremyscook.com and we can get this sorted out.

Or this video should show you the details of how to hook it up: https://www.youtube.com/watch?v=AdjU_AVcZTA

small form factor

For EZ Fan Raspberry Pi Fan Control PCB

Being small means easy to find location in case to install. I would recommend the right angle connectors for most smaller cases.
