Robot Control Module "V4" -v1.3

This is a "robot control module" for wifi controlled robots for education and hobby projects. It uses through-hole components so you can easily assemble this board yourself from affordable parts.

Alternatives:

An upgrade from the original 3 versions of RCM boards

Here are smaller and more powerful RCM boards: BYTE and NibbleDocumentation, 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

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!
