Seeed Studio Solar Charger Shield V2.2 for Arduino

The Seeed Studio Solar Charger Shield V2.2 for Arduino is a stackable power management shield with a 600mA output at 5V for Arduino-compatible platforms. It enables adaptive battery power management and acts as an efficient energy harvester for in-field charging in remote or portable projects.

Overview

This shield supports a wide range of batteries with voltages between 3.0V and 4.2V, boosting their output to a stable 5V. For autonomous operation, it can be paired with a Li-ion battery and a solar panel to create a self-sustaining sensor unit. The board can deliver a maximum current of up to 600mA, providing power for connected components. Its compact footprint of 68 mm x 53 mm allows it to stack neatly onto an Arduino board without requiring excessive space.

Charging and Status Indication

A built-in Micro-USB connector allows convenient battery charging from a standard USB power source, with a continuous charge current of up to 900mA. A red LED signals that charging is in progress, and a green LED indicates a full charge. For safety, the shield incorporates short-circuit protection.
