Setup Notes (from shown UI text)
- Betaflight Ports note shown: “Note: not all combinations are valid. When the flight controller firmware detects this, the serial port configuration will be reset.”
- Betaflight Ports note shown: “Note: Do NOT disable MSP on the first serial port unless you know what you are doing. You may have to reflash and erase your configuration if you do.”
- Example shown highlights selecting a UART peripheral as “Blackbox logging” with a value shown as 2000000.
- Blackbox configuration items shown include: Serial Port; 1/1 (2kHz); GYRO_SCALED; All selected; Save and reboot.
Applications
- FPV drone tuning and flight log recording for micro drones
- Betaflight / INAV blackbox logging and analysis (compatible with tools such as Blackbox Explorer)
- Works independently of FPV video system type (analog or digital)

Details

Flywoo’s OpenLager Nano black box pairs with the BBITF USB-C reader for a compact, plug-and-play setup with 512MB onboard flash.

The OpenLager Nano module weighs about 0.4g, helping keep ultra-mini drone builds light and space-efficient.

The 512MB flash memory chip provides extra storage space for saving multiple sets of flight data.

The Blackbox module plugs into the flight controller with 4.5V, GND, TX2, and RX2 wiring and connects to the BB/TF USB Reader V1 for downloading logs to a computer.

Betaflight setup assigns Blackbox logging to the connected UART and lets you open the saved log file in Blackbox Explorer for review.
