HDZero AIO15 2-3S 15A (FC+ESC+ELRS+HDZero)

HDZero AIO15 is an AIO board designed for small 2–2.5" toothpick drones powered by 2–3S batteries. It is the first board to integrate a flight controller, ESCs, ELRS receiver, and an HDZero digital video transmitter. At its core is an STM32G473 processor paired with an ICM42688P gyro. The ESCs run Bluejay firmware and can handle currents up to 15A, making the board suitable for motors up to 1404 size. The built-in ELRS receiver uses a wire antenna and is connected via UART.

The most distinctive feature is the integrated HDZero digital VTX with up to 200mW output power. The VTX connects via a u.FL antenna connector and includes an analog HD composite video input. The board also features a 5V 1A BEC, a current sensor, and motor connectors for easier installation. It uses the standard 25.5x25.5mm mounting pattern. Connection to a PC is done via an external USB-C connector.
