HDZero AIO5 is a board designed for the smallest 65mm Tinywhoops. The board is the first to integrate a flight controller, ESCs, ELRS receiver and HDZero digital video transmitter. The flight controller is based on the F411 processor in combination with the ICM42688P gyro. The ESCs use BlHeli_S firmware and can handle current up to 5A. The board is thus suitable for motors up to size 0802. The integrated ELRS receiver uses a wireless antenna and is connected via the SPI. The most interesting part of the board is the integrated HDZero digital video transmitter with a power of up to 200mW. The transmitting antenna is connected via a u.FL connector. The HDZero transmitter has an analog HD composite video input. The board also features a 5V 1A BEC and a current sensor. There are also connectors for easier connection of motors. The board has conventional mounting holes with a 25.5x25.5mm pitch.
