Very, very impressed with ESP32andmore and this fan control board. I had a "novice" user issue getting the Dallas sensors to work and Frank really went above and beyond to get me sorted out. This board solves the exact cabinet cooling problem I have and I could not be happier. Would buy from him again 1000%.

Solid product, easy to configure

For ESP32 Control Board Ver. 2.1

I have been looking for exactly this to control the fans in the rack for my home lab. Solid easy to configure product that even does a bit more than I need. Support when you make a mistake is way better than most in this day and age.

Awesome Board!

For ESP32 Control Board Ver. 2.1

Purchased 2 of these boards. They work perfectly. One for a 3d printer enclosure and one for a network rack. The support I received from this seller was second to none. I will purchase again. Shipping was super fast. Thanks so much!

It works!

For ESP32 WLED Four Channel Controller

It's alive! https://i.imgur.com/xxmMIjO.jpeg

Setup was quick and easy using the WLED app on Android.

I'm dubious about the barrel connector being able to take the full 12 amps (e.g. Mouser's selection of barrel plug parts tops out at 8A ratings), so I'll be injecting power to the LED strips directly instead (I'll have 1,800 LEDs).

Thank you for your review. Very cool matrix. Six times the size you show in your photo!! Please let us know what like for refresh rate you get with WLED with the 1800 LEDS. In regards to the current rating, the board's copper is rated at 12 amps given a 30C temp rise. Each of the KK-style connectors is rated at 7.5 amps (but if you actually measure the conductor and by calculation it can handle 16 amps). There are four. The fuse is rate at 12 amps. The barrel connector we use is rated at 8 amps but looking to the actual copper the ground conductors can handle 30+ amps and the center pin, 40+ amps (this is the IPC-2152 for short conductors). The limit with these connectors is the ground contact with the plug, difficult to calculate. Since I routinely see 10 amp power supplies with the same barrel connector (https://a.co/d/fc3LVsZ) and have seen 12 amp versions, we decided to test the connector and board. We ran the barrel connector under a 15amp load for an extended period and it was not damaged. We also tested the board loading 2 KK-style connectors through the barrel connector @ 12amps and tested fine.
I would use the 12 amp number as a rule of thumb to size the number of LEDS since rarely are you using 20ma per LED (3 channels full on) and that works out to be 600 LEDS. And I would similarly size your PS according as you never want to draw full amperage rate of a PS. And in your use case 1800 LEDS full on you are looking at 48 amps, so power injection is the only viable option given also any controller board. Your feedback was much appreciated and good luck with your COOL project!!

Quality design, does what it says and does it well

For ESP32 Control Board Ver. 2.1

I run a rack and Home Assistant at home. The rack needs cooling, and I want the cooling to be quiet and integrated into Home Assistant. This board helps to do exactly this: take a power plug, 4 PC fans, and integrate those together into Home Assistant.

The board is very well designed, a lot of effort has gone into crafting the features - from onboard power regulation (can power from 12V), to screw terminals to expansion IO headers (which allowed me to add a I2C screen with no hassle). It ships with essential documentation on pinouts and general instructions. Overall, I've had zero problems with it, everything works seamlessly. The example ESPHome firmware configuration in GitHub is very helpful as a starting point for customization (I've added ALARM detection logic, in case RPM drops unexpectedly).

Overall, very satisfied - a small, well designed solution that is surprisingly flexible. Thanks!

Great! Does what it says and does it well

For ESP32 Control Board Ver. 2.1

I bought this for managing the fans in my network rack and it does a great job at that. Multiple probes allow for averaging the temperature so you can get a better idea of the overall temperature, and multiple fan ports allow me to both circulate and exhaust.

My only suggestion (and limitation of the board) is that the output could be higher. A lot of the high CFM exhausting fans I was looking at were well over the total limit of the board.

Rob,
Thanks for the kind review. We surveyed high flow fans and fell upon the Noctua NF-A14 at 160 cfm which pulls 0.60 amps max and have run 8 of those on the board. We would be interested in what fans you are using. For our latest production run of the board we did a revision increasing the current handling and fusing to 12 amps which is only limited by the barrel power connector. For your application, if run into any tripping of the resettable fuse, let us know (esp32andmore@gmail.com)

Awesome board

For ESP32 Control Board Ver. 2.1

I'm using this in my server closet, replacing a simple PWM fan controller board with no real logic on it.
Setting it up with ESPHome was a blast, the GitHub page gave me all the information I needed.
Running smoothly since then.
Good board, good 3D printed case, good documentation.
Awesome work guys! Thank you very much!

Perfect 10

For ESP32 Control Board Ver. 2.1

First of all the shipping was super fast, got the item within 2 days. I have been testing this board for a week now, and it works just perfectly. Previously I used to have a breadboard+buck converter for a similar console fan setup, it was all cluttered and not very safe. This board was suggested by someone in ESPHOME discord and I wanted to give it a try. This is a perfect 10 in my book, components used are pretty good, the ESP32 board is also solid, and No wifi drops yet. ( I have more than 8 ESP32s from various vendors most of them drop wifi, every hour. I think there are resistors in the board for the Dallas sensors, I use a long cable and a short one, but they never got disconnected.
So much thought process has gone into this design and a lot of expansion possibilities. I use an RGB PWM fan which I can control the light color and brightness depending on the fan speed.

Overall a very well-designed board, with many functionalities. Will buy it again. Great job Guys!!
