Description
Board that allows you to power the Arduino module using the battery LiPol 1S 3.7 V Built-in transducer provides a stable voltage of 5 V. The module uses three chips: MAX17043G+U (documentation) - monitor of state of charge, MCP73831T (documentation) - charger TPS61200DRCT (documentation) - converter step-up.
The Arduino board and lithium-polymer rechargeable batteries can be purchased separately.
Built-in battery charger
The system also has battery charger LiPolwith a current of 100 mA powered via the miniUSB port. After adding the resistor, the charging current can reach to 500mA.
Monitor of discharge
Monitoring the state of charging of the battery is carried out through the system MAX17043G+U connected to the I2C bus (pins A4 and A5). It has a configurable alarm which warns about reducing the power below 32 %.
