Open firmware
The device is an ESP32-S3 and the firmware is fully open source. Flash our releases, or build your own.
Building from source
$ git clone github.com/tinytradedesk/firmware
$ pio run -t upload
MIT licensed. Custom builds are welcome — the hardware is yours. Flashing third-party firmware doesn't void the 14-day DOA coverage, but we can only support our own releases.
