          Tips

          • If GPS, Receiver or other peripherals are connected to UART2(Tx2,Rx2)  and these peripherals are powered ON while connecting USB.   STM32G474 will not go into DFU mode. It is related to DFU protocol used in the STM32G474 bootloader.  Pls unplug peripherals from UART2 before you try flashing the FC.

          • If using Frsky SBUS+SmartPort receivers. you may remap one of PWM pins to softserial_tx for SmartPort, e.g.  LED pin, “resource serial_tx 11 A15”, “feature softserial”.

          • Due to leakage voltage on MCU I/O, there is floating current readout when no external current sensor connected.  If you don’t use external current sensor.  “set current_meter = NONE”.

          • There is no UART4 breakout on this board.
