TL;DR
The M5Stack Core2 IoT controller has been outfitted with open-source firmware that mimics the functionality of OpenAI's Codex Micro macro pad. This project was developed by IAMLIUBO, allowing users to monitor and control AI coding agents more efficiently. The original Codex Micro is a well-designed device with a CNC-milled enclosure, rotary encoder, and joystick, but its $230 price tag and limited availability make it less accessible for many.
