Hello

Twice a day, that's a record.

I always lost power in RTC DS3231 when Disconnect the Feather MO, I use 3V CR1225 COIN.

vin - 3v
Gnd - Gnd
Scl - pin 21 scl
sda - pin 20 sda
bat - Ublox pam 7q

I'm sure I'm missing something

Can I get help

thenks

Hi again

Do you recommend adding I2C? (I use 1 LCD and 1 RTC on same pin on MO)

I2C use SERCOM 3 (pads 0 & 1)

Thanks

eli
