Good Morning

how can I use 'Allows RTC - Real Time Clock' in Olimexino 32u4 ?

Hello brunello,

You have two options - either remove Q1 and solder RTC there or you can add additional clock on Digital connector pins D10 and D11. D10 and D11 go straight to OC4B and OC0A processor pins. Still refer to the ATMega32u4 datasheet to see if the OC4B and OC0A are a legit choice for RTC.
