Description

RCMhardwareNibble-v1.8

https://github.com/RCMgames/RCM-Hardware-Nibble/

The RCM Nibble is the smallest board in my series of small robot control circuit boards.

It is powered by an ESP32 chip so it can communicate over WiFi. Any robot the RCM Nibble is in can be controlled by a computer by communicating over WiFi.

The board also includes an ICM20948 IMU!

1.08 by 1.12 inches, 27.432 by 28.448 millimeters
4 motors
4 servos
2 additional GPIO pins
built-in IMU
battery monitoring
I2C connector on QT PY
runs on 3-11 volts

program with RCMv2 https://github.com/RCMgames/RCMv2

Tested with the following types of Adafruit ESP32 QT Py:

S3 with 2MB PSRAM
S3 with 8Mb Flash
S2
