A raspberry pi pico expansion board designed for OpenTrickler project

The Raspberry Pi Pico Motor Expansion Board V2 vis designed to be used as the controller for OpenTrickler. The board is designed to trickle certain amount of charges (e.g, gun powder) from the reservoir by reading measurements from the attached precision digital balance and actuate corresponding motors.
