The JHEMCU GS405A AIO features an F4 FC and a 5A ESC with built-in ELRS 2.4GHz receiver. This is an ultra-light 3.3g brushless AIO flight controller with 25.5x25.5mm mounting pattern!! 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 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. 

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.
• ELRS firmware target is DIY_2400_RX_ESP8285_SX1280
• Onboard a WS2812 LED light, and WS2812 LED pads
• Built-in ELRS 2.4GHz Receiver
• F4 Flight Controller
• 5A 1-2S ESC

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 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.
