CN3065 Mini Solar Charge Module

Advanced Solar Energy Harvesting Architecture

The CN3065 Mini Solar Charge Module is an engineered single-cell lithium battery management board tailored specifically for solar power harvesting and off-grid remote applications. Built around the high-performance CN3065 constant-current and constant-voltage (CC/CV) charge controller IC, this compact module dynamically monitors and regulates input energy harvested from small photovoltaic panels. By automatically managing voltage levels and charge currents, it ensures safe, maximum-efficiency power transfer directly into standard 3.7V nominal (4.2V fully charged) Lithium-Polymer (LiPo) or Lithium-Ion (Li-Ion) batteries.

Precision Charging and Adaptive Power Control

Designed to operate seamlessly within an input voltage window of 4.4V to 6V, this module matches perfectly with standard 5V and 6V solar panels. The onboard CN3065 integrated circuit features internal power MOSFETs, intelligent charge current regulation, and adaptive power control. By default, the board delivers a steady continuous charging current up to 500mA, ideal for maintaining single-cell batteries without risking thermal degradation. Dual visual status LEDs (red for active charging and green for charge completion) provide instant diagnostic feedback. For hybrid charging solutions, an integrated Mini-USB port allows auxiliary charging via standard USB power sources when sunlight is unavailable.

Robust Protection and Circuit Connectivity

Safety and stability are paramount for unattended solar installations. The module includes robust built-in safeguards, such as short-circuit protection, overcurrent limiting, and thermal regulation that reduces charge current if internal temperatures rise. The interface includes standard 2-pin JST PH2.0 connectors for hassle-free solar panel and battery attachment. Load devices are connected in parallel with the battery, allowing the module to pass power continuously to downstream electronics while concurrently replenishing the energy reserve.

Versatile Remote and IoT Applications

This mini solar charger is an optimal solution for low-power IoT microcontrollers, remote environmental monitoring stations, automated agricultural sensors, outdoor wireless mesh nodes, wildlife tracking deployments, and solar-powered robotics. Its lightweight footprint and maintenance-free design make it ideal for space-constrained, long-term outdoor field deployments.
