6 FAQs about [Lithium battery to power the microcontroller]

Can a microcontroller read battery voltage over UART?

Two 100KΩ resistors also form a voltage divider for the microcontroller to read the battery voltage through pin A0's ADC channel, and I'm planning to add an example firmware which reads and prints the battery voltage over UART in the near future.

What connector is used for a lithium battery?

Can a mcp73831 charge a Li-ion battery at the same time?

The problem with charging and using a Li-ion battery at the same time is that end of charge is not properly detected. The MCP73831 uses the current level at the end of the constant voltage stage for charge termination. Aha that makes sense, thanks for clearing that out. I think i will leave the schematic as it is and not remove the switch.
