The RTC Logger Shield includes the following features:

Micro SD Card slot
2x STEMMA/QT connectors with 2 sets of IO - Can be used for I2C devices or UART or anything else you feel like

JST PH connector for easy battery connection
RTC Interrupt pin is connected to an RTCIO pin on the Tiny board, so you can wake your board from deep sleep with the Alarm
RTC Interrupt pin can be disconnected to it’s IO by cutting the trace on a solder jumper on the back of the board
RTC Clock output is disconnected to it’s IO pin, but via a solder jumper on the back of the shield, so you can solder bridge it if you want to use it, or leave it disconnected to are up the IO for other uses

What libraries do I need?

The RTC Logger shield works with the standard ESP32 SD card library.
For the RV-3028-C7 RTC, I recommend the RV-3028-C7 Arduino library by Macro Yau
