3 weeks ago Here is my modified usb_helper which automatically chooses the right values for the M5Stack Core, Core2, and Core3SE. You can see the pin numbers in each line, then look at the chart on the USB shield to choose the right DIP switch to match.

Hi, could you let us know what DIP switch config we should use for CoreS3, the documentation isn't so clear. Thanks in advance :)
