Happymodel SuperX V2.1 is an AIO board designed for the smallest and lightest Tinywhoops or Toothpicks. The board combines a flight controller, ESCs, ELRS receiver and video transmitter. The board has 25.5x25.5mm mounting hole spacing and supports 1S battery power. The board is equipped with a current sensor.
The basis of the flight controller is a F411 processor combined with a BMI270 gyro. The ESCs use Bluejay firmware and can handle current up to 5A. The integrated video transmitter uses OpenVTX firmware and supports power up to 400mW. The FPV antenna can be connected via a u.FL connector. The integrated ELRS receiver has a fixed wire antenna. The ELRS receiver is connected via UART and uses a 2.4GHz frequency. The same UART is used for communication with both the video transmitter and the ELRS receiver.
