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

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

The flight controller uses a STM32G473 processor combined with a ICM42688 gyro and a DPS310 barometer. The ESCs use modern AM32 firmware and can handle up to 45A per channel. The integrated ELRS receiver operates at a frequency of 2.4GHz and connects via UART interface. The board is designed 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 includes a protected 8V/3A BEC allowing direct powering of HDZero, DJI, Walksnail, or OpenIPC units. 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.
