HDZero Gamma 3-6S 45A AM32 (FC+ESC+ELRS RX)

HDZero Gamma 45A is an AIO board combining flight controller, ESCs, and ELRS receiver. The board is suitable for smaller 2.5–4" drones powered by 3–6S LiPo batteries.

The flight controller uses an STM32G473 processor combined with an ICM42688 gyro. The ESCs use modern firmware AM32 and can handle current up to 45A per channel. The integrated ELRS receiver operates at a frequency of 2.4GHz and is connected via UART interface. The board is intended for use with digital video transmission and is therefore not equipped with a chip for analog OSD.

The board features a connector for digital video transmission. It has a protected 8V/3A BEC and allows direct powering of units like HDZero, DJI, Walksnail, or OpenIPC. A second 5V/3A BEC is intended for peripherals such as LED strips, buzzers, or GPS modules. The board is equipped with a current sensor.
