Description
FNAF Head control board for raspberry pi pico WH
I use it for a FNAF Foxy head it has 2 sockets for LED Common(-) RGB LED's which are tied to operate together and 2 sockets for 2 Servo motors and its compatible with the raspberry pi pico board and it has a AUX socket for things like a fan or a speaker for inside the head of your cosplay
