Lipo Rider V1.3

Introduction

Power your favourite electronic kit with green energy! The Lipo Rider board allows you ride the solar wave to

run your favourite 5V device. The Lipo Rider board is the ideal green power solution for your outdoor sensor

design. Attach the Lipo Rider board to your sensor board and it can run on solar power forever!

The LipoRider is extremely affordable and easy to use. No programming is required. Plug it in and it works. The

internal charger IC handles all the power flow between the various components.

In case solar power is not sufficient, the microUSB port allows you to charge your lithium battery through USB.

It can also be used to program your kit without detaching the Lipo Rider board.

The Lipo Rider can be purchased as a separate board or as a kit (Lipo Rider + Lithium Battery + Solar Panel)

from Seeed Studio.

Features

 Jst 2.0 connector

 Stable 5V USB power supply regardless of source

 Charge/Recharge algorithms built into chip

 Charge Lithium Polymer Battery through solar power or USB

 Stable supply voltage through either lithium battery or USB

 2 x USB ports let you program your kit while charging your Lithium battery

1. Lithium Battery Full 2. Solar Panel voltage outside of range (most likely due to insufficient solar power). In the second case, re-position your solar panel to accept more sunlight if possible. None of the above conditions will prevent the Lipo Rider from providing a steady 5V supply to the USB, unless the battery is flat. Solar Panel Equations Solar Panel Output Power = Output current × Supply Voltage e.g. 1W = Iout× 5V Iout = 200mA Therefore, charging for 1 hour will give 200mAh, ignoring losses.

Example Outdoor Sensor Device Power Supply One important application of the Lipo Rider board is as an affordable power supply for outdoor sensors. The outdoor sensor device will be powered by the lithium battery supplemented by the solar panel. Please note that it is not recommended to run the outdoor sensor ONLY on solar power, as this may vary during the day and may cause the sensor to reset / power down unexpectedly. In this case, the device is running in “USB Mode”.
