Hi,
I purchased 3 Gemma v2, invoice # 1452711, 2 of them work perfect, 1 cannot be programmed. I get a USB failure message. I think this one is DOA. I would like to get a replacement Gemma v2. Please email me and let me know how to arrange for a replacement.
Thank you, Jack
Gemma v2 can not communicate over USB

What does the red LED do when you press reset?

When I press the reset button the red LED does nothing, it does not light up or flash. This one acts like it is dead. The other 2 work perfect.adafruit_support_rick wrote:What does the red LED do when you press reset?
