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, furaisanjin
