The Flywoo GOKU F405 HD is a compact AIO flight controller designed for the smallest 1S Tinywhoops with digital video transmission systems such as DJI O4 or Walksnail Avatar. It integrates a flight controller with an F405 microprocessor, ICM42688P gyro, and SPL06 barometer for altitude measurement, 5A ESCs running Bluejay firmware, and a built-in 2.4GHz ELRS receiver. The board also features 8MB of blackbox memory.
For easy motor connection, the board is equipped with JST1.25 connectors. When used with the DJI O4 unit, a Flywoo 5V step-up BEC is required. In this configuration, the board can operate down to a minimum voltage of 2.6V.
