Description

Robot-Control-Module-V4 V1.3

Documentation, KiCAD, Arduino software libraries, and more are all on GitHub: https://github.com/RCMgames/RCM-Hardware-V4

4 motors and 7 servos OR 6 motors and 3 servos
3 additional input only pins
runs from 5 NiMH AA batteries OR (need to test) 4.5-22v with the addition of voltage regulators (see list of components)
Qwiic connectors OR two more GPIO pins
all components are hand-solderable through-hole parts except for the Qwiic connectors which are surface mount

Compatible with 38 pin devkitC ESP32 boards

program with RCMv2

Alternatives

An upgrade from the original 3 versions of RCM boards

Here are smaller and more powerful RCM boards: BYTE and Nibble

I would like to thank PCBWay for sponsoring prototyping runs of this project. PCBWay produces very nice boards, supports open source hardware, and gave me great support as I worked on this project. Special thanks to Liam!
