Description

This module is intended to host a ESP32 WORKIT MCU, and use ESP32 LEDC feature to drive 12 servos. I designed it to be used in a 4 legged spider robot. Other pins are exposed via a 16 pin header. There is also a power connector that is meant to be hooked up to a 4.8V NiMH battery, providing power for the servo as well as the MCU.
