Hi all,
I very recently started my journey with Adafruit microcontrollers ordering a Trinket M0, a Gemma M0 and a Feather Feather 328P from Berrybase in Berlin, Germany (their support asked me to mention this here). While the Trinket M0 worked well with both Circuit Python and Arduino IDE, programmed and running as intended, I have a serious issue with the Gemma M0.
I unboxed it and connected it to my laptop using the same cable and USB port as with the Trinket (that should rule out any cable / port issues). Nothing happens, no LEDs, nothing in the file explorer, no USB com port opened, nothing in Arduino IDE. Same with plugging in a freshly charged LiPol battery. When connected to USB, I can measure 5V as expected between ground Vout pins, so there is voltage at least at the input. I did nothing with the board apart from connecting power.
Does anyone have a hint on what to do? Can I recover the Gemma M0 back to normal operation?
edit: and yes, I did try in both Off and On position of the on board switch

Re: Gemma M0 not working
Can you get into bootloader mode by double-pressing reset?

Re: Gemma M0 not working
no, unfortunately not. I did another voltage measurement, when switched on, the two pin pairs on the ON side of the switch have close to 5V, so it should be neither voltage supply nor ON/OFF switch

Please post a clear photo of the component side of the board.

Nothing jumps out at me. Please email [email protected] with a link to this thread, your order number, and request the replacement of one Gemma M0.
