Looking for a new way to power your Arduino projects? All you need is a photovoltaic cell, a single-cell LiPo battery and this small Arduino-compatible module. Its job? To supply you with the maximum amount of available energy thanks to its 2 amp LT3652 circuit. You can easily obtain a maximum charge current of 450 mA with a recommended maximum input voltage of 20V.
It’s not particularly difficult to use. Simply connect your solar cell on one side of your Sunny Buddy and your rechargeable single-cell LiPo battery on the other. This solar charger module not only has 2-pin JST connectors but also unpopulated areas allowing you to install a 3.5 mm screw terminal to add your own personal touch!
