JHEMCU GSF405A is a 1-2S F4 AIO with integrated 4-in-1 5A ESC and ELRS 2.4G receiver. It has 5 serial ports (UART1, UART2, UART3, UART4, UART6), one I2C port, and one SBUS interface. (The serial port used by SBUS is RX2), onboard a WS2812 LED light, and WS2812 LED pads. Also built-in 8MB blackbox and BMP280 barometer, buzzer interface, camera interface.
GSF405A AIO FC has the built-in full ELRS receiver, connected on the UART1 port. It is not an SPI receiver, so it the ELRS firmware can be updated via Wi-Fi or Betaflight serial passthrough. ELRS firmware target is DIY_2400_RX_ESP8285_SX1280.
And the board weights only 3.3grams (without antenna).

1. Connect USB to power the flight controller. After inserting the USB for the first time, disconnect the USB as soon as the LED on the receiver turns off. Repeat the operation twice, when the USB is inserted for the third time, the LED will start to flash double, and the receiver will enter the binding mode.
