I am very disappointed to learn that the RS485 port on the M5Station is linked to UART0 GPIO1,GPIO3, so is shared with the USB.
For example I want to use the M5 station for industrial application that uses modbus, and I also need Serial 0 for debug.
So I can't do nothing now.. and I liked the device.
