v2.0 · MicroPython · open source

A python operating system, in a pocket-sized badge.

OreoOS runs 20+ apps on a breadboard ESP32-S3 — a launcher, an on-device app store, OTA updates over WiFi, file transfer over USB, IR-quest peer-pairing, and a Tamagotchi panda that judges you for skipping meals.

Four things make the badge feel alive

Python all the way down

MicroPython on ESP32-S3. Apps are a manifest.json + main.py — write one in ~30 lines and it shows up in the drawer.

Files over USB, guarded by a code

Open Transfer on the badge, run `oreo transfer send`, type the code it shows. No Wi-Fi setup, and nothing listens on your network.

Peer presence (soon)

BT will return for proximity-based features — IR-quest assists, sync gestures, badge-to-badge nudges.

Video, built for the hardware

RV565 combines full-colour independent frames, firmware inflation, and a proven 24 FPS native DMA display path.
