5 serial ports (UART1, UART2, UART3, UART4, UART6), one I2C port, and one SBUS interface.
Built-in 8MB blackbox and BMP280 barometer, buzzer interface, camera interface.
ELRS firmware target is DIY_2400_RX_ESP8285_SX1280.
Onboard a WS2812 LED light, and WS2812 LED pads.
This is an ultra-light 3.3g brushless AIO flight controller with a 25.5x25.5mm mounting pattern.
The JHEMCU GS405A AIO features an F4 FC and a 5A ESC with a built-in ELRS 2.4GHz receiver. This FC can handle 5A of continuous current and up to 2S. This AIO also features a built-in 8MB blackbox, buzzer interface, and camera interface. GSF405A AIO FC has a built-in full ELRS receiver, connected to the UART1 port. It is not an SPI receiver, so the ELRS firmware can be updated via Wi-Fi or Betaflight serial passthrough. Features: 5 serial ports (UART1, UART2, UART3, UART4, UART6), one I2C port, and one SBUS interface. Built-in 8MB blackbox and BMP280 barometer, buzzer interface, camera interface.

Specifications: Main Material: PCB Board, Electronic Component Color: Black EXPRESSLRS 2.4GHZ Receiver Slow flashing: No transmission signal received Firmware: DIY_2400_RX_ESP8285_SX1280 Working Agreement: CRSF (Betaflight) ELRS receiver indicator status: Steady on: Received transmit signal Double flash: code matching mode Frequency: 2.4GHZ ELRS Linking Steps 1. Connect the USB to power the flight controller. 2. After inserting the USB for the first time, disconnect the USB as soon as the LED on the receiver turns off. 3. Repeat the operation twice. 4. When the USB is inserted for the third time, the LED will start to flash double, and the receiver will enter the code matching mode.
