gemma 2 not loading under IDE

by mikee on Mon May 25, 2020 10:37 pm

I just purchased some gemma 2 boards followed the instructions for loading a :"blink" sketch to the board to test. selected Arduino gemma and the USBtinyISP functions. I pressed the bootloader button and loaded code while red led is blinking the ide has error: "serial port does not exist. board may not be connected" updated all libraries too
any ideas what could be wrong? appreciate any help

Do you have a black or teal Gemma? If you have a black one, then make sure to select Adafruit Gemma:
