JHEMCU GSF405A-BMI is a 1-2S F405 AIO that integrates a four in one brushless and ELRS 2.4G receiver. It has five serial ports (UART1, UART2, UART3, UART4, UART6), one I2C port, and one SBUS interface (SBUS uses RX2 serial port). The built-in ELRS receiver is the UART1 port, and there is a WS2812 LED on board, with a reserved WS2812 interface. Built in black box 8MB and barometer, with buzzer interface and camera interface. A 5V powered camera interface is reserved on the board.

Flight control firmware: Betaflight_ 4.3.0_ STM32F405.HEX (JHEF405PRO)

 

Weight: 3.3 grams

 

ELRS parameters:

 

Frequency: 2.4GHZ

 

Work Agreement: CRSF (Betaflight)

 

Firmware: JHEMCU_ EP24S_ 2400_ RX-3.0.0.bin

 

ELRS receiver indicator status:

Frequency matching steps:

 

1. Connect USB to power the flight control. After inserting the USB for the first time, disconnect the USB immediately when the LED light on the receiver goes out. Repeat the operation twice, and when the USB is inserted for the third time, the LED will start to double flash, and the receiver will enter code checking mode.
