Notes

The solar charger is a stackable shield to Arduino compatible platforms, enables adaptive battery power and act as energy harvester for in-field charging. You may use various batteries that has the voltage of 2.7V-4.2V to shift up for 5V output, or put on Li-ion battery and solar panel to form an autonomous sensor unit. The maximum current provided by the board can get up to 700mA. An USB connector is also useful to charge the battery.

Features

  • Short circuit protection
  • Battery status indication (Red: Charging, Green: Charged)
  • 5V via USB port for powering small devices like USB Lamp, Cooler pads etc.

Usage

Solar Panel

Solar panel is one of the most common green power sources we use. The typical output of one unit is around 5V. Plug solar panel into JST socket on the shield as below.

Note: Make sure there is sufficient light to provide considerable current.

Charge using solar panel

Now, press down SW2. You will find the "Charge" indicator LED lights up. The other indicator "Capacity" indicates remaining power of battery. When the remaining power is below 30%, it turns red. When remaining power is between 30% - 80%, it turns yellow. Otherwise it's green. Remaining Power Indicator
