CN3065 Mini Solar LiPo Charger MPPT Module

The CN3065 Mini Solar Charger Module is a compact and efficient solar-powered lithium polymer (LiPo) battery charging board built around the CN3065 IC, featuring built-in Maximum Power Point Tracking (MPPT) technology. Designed for solar energy enthusiasts, IoT developers, and embedded systems hobbyists, this module enables reliable LiPo battery charging directly from a small solar panel — making it an ideal power solution for off-grid and outdoor projects.

The integrated MPPT algorithm continuously optimises the power drawn from the solar panel, ensuring maximum charging efficiency regardless of varying sunlight conditions. Onboard charge status LEDs provide real-time visual feedback, while the built-in overcharge protection safeguards your battery from damage during extended exposure to sunlight.

Whether you’re powering a remote weather station, a wireless sensor node, or a portable IoT device, this miniature module offers an elegant, all-in-one solar charging solution with minimal external components required.
