Alpha (pre-release) build.

What are you updating?

Before you start

For OpenFC-Lite. The Lite Mini file comes later.

  1. Back up your config: save diff all in the Betaflight CLI. Flashing resets settings.
  2. Props off, battery out, USB only.
  3. Computer only (Chrome/Edge), data-capable USB cable.
  4. On a new board: test on USB before soldering.
OpenFC-Lite: Betaflight 2026.12.0-alpha (d593400), SHA-256 cf94838

Betaflight is GPL-3.0. Source for this build: Betaflight, config. OpenFC-Lite: target OPENFC_LITE_RP2350B, config a2b6666.

Other ways

Pick a board first.

Hold BOOT while plugging in USB, then copy the file onto the RP2350 drive. The board restarts by itself. Check the name printed on the board first: this method can't stop a wrong file.
