TunercFPV EZ3 1-2S HD AIO is a compact AIO board for toothpicks and cinewhoops with digital video transmission. The AIO board integrates flight controller, ESCs, and UART ELRS receiver in one.
The flight controller is based on the AT32F435 processor augmented with the ICM42688P gyro. The board also features 8MB memory for blackbox and an integrated DPS310 barometer for altitude measurement. It has a 5V/0.5A BEC for powering the board itself and the possible GPS module, and a 9V/2A BEC for powering digital video transmitters. The board uses an external USB-C connector.
The ESCs use Bluejay firmware and can handle current up to 12A. They are suitable for motors up to size 1404. The board allows powering from 1-2S Lipo/LiHV batteries with a voltage range of 3.2–8.9V. It also includes a current sensor.
The integrated ELRS receiver is connected via UART and can be fully configured like any external ELRS receiver. Furthermore, the receiver is equipped with PA (power amplifier) and LNA (low-noise amplifier). The ELRS antenna connects via an IPEX1 connector.
