Charging Modules

Charging modules manage the safe charging of lithium batteries in embedded projects, handling constant-current and constant-voltage charging profiles, overcharge protection, and charge status indication. They allow a rechargeable battery to be integrated cleanly into a portable build.

The range includes TP4056-based single-cell Li-ion chargers with micro-USB, USB-C, and solar panel input options, as well as modules with integrated load-sharing circuits that allow simultaneous charging and use.

Charging modules are used in portable Arduino and ESP32 sensor nodes, wearable electronics, DIY power banks, battery-backed IoT devices, solar-powered remote monitoring systems, and any project that needs a self-contained rechargeable power solution.
