Re: DS1307 on rpi4B

Hello.

I'm using this module (
https://www.electronicwings.com/sensors-modules/real-time-clock-rtc-ds1307-module)
and there are R2 and R3 for pull-up on the module. The registers are
connected to 5V. This probably harms RPI4B because the voltage is 3.3V at
RPI4B side. So I removed R2 and R3. That's why internal pull-up is required.

Best regards,
