The Lipo Rider works as a power module to supply a stable 5VDC power for MCU projects. Here is an example to drive 300mA output wave for a power supply:

Hardware Setup

Lipo Rider provides a reliable solution to charge a Li-Po battery from solar or USB power and output a boosted 5VDC power to the standard USB port. When the mini USB power socket is connected, it will charge the Li-Po battery and disable the boost circuit so that the mini USB power is directly output to the standard USB socket. When the solar JST power socket is connected, it will charge the Li-Po battery and boost the Li-Po battery power to the standard USB port.

This is the hardware setup example for the Lipo Rider. When you put the setup under illumination, the solar panel collects the luminous energy and charges the Li-Po battery, Lipo Rider boosts the Li-Po battery power to 5v for Seeeduino or other microcontroller project. The switch is on and the lit LEDs marked by red circle show that the Lipo Rider is working.
