What is it?

This board is an ESP32-S2-based Wifi Fancontroller.

It allows you to control up to 4 independant PWM Fans and read temperature & humdity at the installed location. E.g. you can use a standard 12V 120mm Noctua PC fan as an exhaust for a PC inside a cupboard.

Specs

12V DC Barrel Input (5.5x2.1mm)
4x PWM Fan Output
Integrated HDC1080 Temperature & Humidity Sensor
QWIIC connector
I2C Expansion Port
Neopixel Port (Max. 2A, 100mil / 2.54mm PTH header)
3 User Buttons
GPIO Expansion Pads (2.54mm SMD on bottom)

Why did you make it?

When I built my first rack, I found no readily available solution for controlling PWM fans via HomeAssistant. That's when I decided to make this product.

I'm using it in my network racks for ventilation. Put 2x 120mm PWM fans on top for exhaust, add a internal fan for circulation and you're good to go.
