The RTC Board
Introduction
The battery board is a simple Lithium Battery charger and power supply. It has an ultra low power LDO (Low DropOut Regulator) to generate 3.3V from the battery input. It works nicely with the Platform Board or right into your breadboard.
- Uses the popular MCP73831 to handle the battery charging
- Ultra Low Iq (~2uA) Linear 3.3V Regulator MCP1702
- Robust Micro USB connector for charging and standard JST connector for battery connection
- Breaks out the USB 5V in for detection or as a separate supply, also Battery Voltage is available for fuel gauging... or again as a separate supply.
