My USB connector broke off the board (Cactus Micro Rev1). I don’t need the ESP8266, but I do need to program the main board. Any help to program the board without usb is appreciated. thanks.
please take a photo of the board. Did the USB connector broke from the board completely?
Yes…usb connector broke clean off – as if someone used a razor blade to remove it from the board. I can’t take photo at the moment (no access to it for a couple days). All contacts beneath the missing usb connector are accessible.
You can only wire the SPI port for programing 32u4 directly. But no idea for the USB port now. It means you can’t program it with Arduino IDE.
