Description

40 Pin Cable ESP32-C3 based Test Platform

This is a test platform with 40 inputs and 40 outputs, using an ESP32-C3 Super Mini module with five 16-bit I2C GPIO Expanders.

By writing test functions to drive specific outputs and read corresponding inputs, connector modules can be docked to the 40 pin headers, allowing cables to be plugged in for testing. Different connector modules allow a wide variety of different cable types to be tested.

The OLED display will show the results to indicate if the cables are wired correctly or have missing/shorted/mis-wired pins.

This is a video showing the concept with a previous hardware version using Arduino Nano, which didn't have enough memory for the project. The video will be updated for the ESP32-C3 version.
