Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•JHEMCU GSF405A-BMI is a 1-2S F4 AIO that integrates a 4in1 brushless ESC and an 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), the built-in ELRS receiver is the UART1 port, there is a WS2812 LED light on the board, and the WS2812 interface is reserved. Built-in black box 8MB and barometer, with buzzer interface and camera interface. 5V power supply camera interface is reserved on the board
