M5 Onboard

Category: Engineering · Sub-category: engineering-misc · Last updated: 2026-05-21

End-to-end onboarding for a freshly-plugged-in M5Stack ESP32 device (Cardputer, Cardputer-Adv, Core, CoreS3, Stick) — detect on USB, flash UIFlow 2.0 firmware, and install the Claude Buddy MicroPython app bundle. Use whenever the user plugs in or wants to flash/provision/reset an M5Stack or ESP32 board, or says "m5-onboard go".

From the source SKILL.md

This skill automates the full cold-start workflow for an M5Stack ESP32 device: detect on USB, identify model, flash UIFlow 2.0, and push a MicroPython app bundle onto /flash/ so the device boots into user software. The apps we ship (Claude Buddy, Snake, Hello) talk over BLE or USB. The workflow runs on macOS, Linux, and Windows; the skill was developed against an M5Stack Basic v2.6 (CH9102 bridge, ESP32-D0WDQ6-V3, 16 MB flash) and generalized to cover the rest of the Core family, with the Cardputer-Adv (ESP32-S3, native USB) as the current default target.
