Circuits Boards & PCB, IoT & Wireless, Power SupplyBattery Shield For WeMos D1 mini battery Charging and Boost
The WeMos lithium battery shield provides a means of powering your WeMos mini, or WeMos mini Pro (see item HCWEMO0002) from a single cell (3.7V) lithium battery. The shield contains a DC-DC converter to step-up the batteries 3.7V to 5V supplying your WeMos mini and shields with up to 1A of power. When the battery is depleted simply plug the shield into a USB power source using a mini USB cable and it will automatically recharge the battery. Two LEDs on the shield indicate when the battery is charging and when charging has completed.

BPW34 Silicon Photodiode Miniature Solar Cell
BPW34 is a PIN photodiode with high speed and high radiant sensitivity in miniature, flat, top view, clear plastic package. It is sensitive to visible and near infrared radiation with wavelength in the range of 430nm to 1100nm. Peak sensitivity is achieved at 900nm wavelength where it’s open circuit voltage is around 350mV for 1mW/cm2 light source. Several of these cells can be connected in series to provide enough voltage to power up an LED or so
