Detailed Information
Happymodel F4 2G4 1S AIO is a small board for 1S Whoops including FC, ESC, video transmitter and RC receiver. The board is thus perfectly suited for small copters, where every gram counts.
The basis of the FC is the F411 processor supplemented with the ICM20689 gyro. Even at this size, the board has not only a voltage sensor (scale 110), but also a current sensor (scale 1175). Controllers with BlHeli_S firmware support 1S battery power and 5A current. They are thus suitable for motors of size 0802-1202.
The video transmission is handled by a video transmitter with OpenVTX firmware and a switchable power of 25-400mW and a u.FL connector for connecting the antenna. The video transmitter is set via the FC with the SmartAudio 2.1 or IRC Tramp protocol.
The receiver is an ELRS 2.4GHz connected via SPI. The receiver has an integrated SMD antenna. The SPI receiver works with ELRS 2.0. Betaflight 4.4 is required for use with ELRS 3.0.
The video transmitter heats up quite a bit. Since it is integrated on the board with the rest of the electronics, we do not recommend leaving the board on for a long time without ambient air flow. If the image drops out, you need to let the unit cool down. In flight, the board is easily cooled by the surrounding air. Do not turn on the board without the antenna connected.
