Features
- RV-3028-C7 ultra low power, super accurate RTC that communicates via I2C
- 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
- I2C1 on the usual I2C pins for the Tiny board you are using
- I2C2 on 2 alternative IO pins for the Tiny board you are using
- JST PH connector for easy battery connection
- On board button connected to the EVI pin of the RTC that you can program to use as an RTC wakeup or to trigger an event
- 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 from its IO pin by default, but you can connect it if you want to use this RTC function by soldering a bridge across the solder jumper on the back of the shield. Left disconnected it frees up the IO for other uses.
