2024-07-11 23:03:13 Hello, it's for the baud rate setting. Have you noticed the baudrate setting switch on the corner of the board. Is it in the right place, e.g. if your code is 115200, then the 3 switchs should be in the position as:A1, B1, SERIAL. Besides, the switch are not good to use, you might need a little strenth to poke it from one side to the other side to make sure it is connected firmly. We will update the switch in the next version.
