Happymodel X12 1-2S 12A AIO (FC+ESC+RX+VTX) Frsky

Happymodel X12 AIO is a small board for 1-2S Whoopy containing 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 by the BMI270 gyro. Even at this size, the board has not only a voltage sensor (scale 110), but also a current sensor (scale 470). ESC with BlHeli_S firmware support 1-2S battery power and current up to 12A. They are thus suitable for motors of sizes 1202-1106 and for less aggressive copters as well as 1404.

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 Frsky receiver is connected via SPI. The receiver has an integrated linear antenna. SPI receiver works under Frsky D8 and Frsky D16 protocols.

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.
