XT60 Plug:

Wemos D1 Mini (V3, Micro USB or Type C)

The Wemos will translate our Button state to a throttle signal for the motor ESC. You can also skip this step and use a Servo tester as your throttle. There is also a version of the base to fit the servo tester instead of the switch. PS: Any other esp8266 will work too.

Just install this .ino File on the Wemos and connect it with 5v, GND and the Data cable of your ESC.

The Data Cable connects to Pin "D1"
The Switch needs to be connected to GND and Pin "D2"

Also you will need some 4s high drain Lipo batteries as the fan will consume about 40-45amps at 16.8 volts.

I use 2 4s 1500mah 65C Batteries.

3D printing settings

minimum of 20-25% of infill. Use Supports.
