M5 Atom Matrix Companion v4 Satellite A single-button control surface for Companion v4 using the M5 Atom Matrix. Includes 5x5 LED-matrix icons for boot, WiFi setup, waiting state and ready state. Supports external RGB LED output on G33 (Red), G22 (Green), G19 (Blue) with G23 as ground. LED colour mirrors the Companion key colour. Features include WiFi configuration portal (hold button for 5 seconds), OTA firmware updates, automatic deviceID based on full MAC address, and full Companion v4 API support including KEY-STATE, COLOR, BRIGHTNESS and PING handling. Ideal for tally indicators, stage triggers, simple control surfaces and event automation tools. Stable codebase aligned with the AtomS3 and AtomS3R versions so all satellites behave consistently.
