Product description: LiPo Charger Plus - Li-Pol 3,7 V battery charger - USB C - SparkFun PRT-15217
The SparkFun LiPo Charger Plus is a charging module designed for single-cell lithium polymer batteries with a nominal voltage of 3.7 V. The module utilizes the MCP73833 controller, supporting charging currents of up to 1000 mA and featuring dual thermal protection. Built-in LEDs indicate power status, charging in progress, and charge completion. The default charge current is 1000 mA (via a 1 kΩ resistor), which can be adjusted by replacing the resistor according to the manufacturer’s guidelines. The charger features a USB Type-C connector and a JST connector for the battery, making it a convenient solution for mobile and IoT projects.
