Trinket M0 battery powered

by Lumas on Mon Jun 03, 2019 8:00 am

Hi everyone,

I'm experiencing a problem with my Trinket M0.
I program the Trinket using Arduino IDE, I build my prototype on a breadboard (with one pressure sensor breakout connected via I2C bus, a buzzer and a led) and all works perfectly.
When I power the board with a LiPo battery (3.7V, 150mAh, from Adafruit) or a 3V coin cell battery, it doesn't execute the sketch.

Can someone help me?

Do you have a
Code: Select all | TOGGLE FULL SIZE
while (!Serial);

or similar line in your setup()?

Yes... ok, I guess that's the problem..
My Trinket is waiting for a serial connection...

Sorry for the waste of time, thank you
