About this product 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. F4 FLIGHT CONTROLLER
