Getting Started
This guide walks you through building a solar powered system, detailing how to connect Li batteries, solar panels, and USB outputs, with tips for ensuring safe and effective operation.
Build a solar powered system
-
Connect the Li battery to BAT IN.
-
Connect the solar panel to SOLAR IN.
-
Connect USB OUT of the module to Arduino with USB cable.
-
Connect all the VCC and GND pins of the peripherals to the regulated power supply headers 5V and GND.
-
Insert the jumper on the ON of the blue header.
Attention
- Each time the BAT IN terminal battery is replaced, the module USB OUT/5V pin header (red) does not output immediately due to the function of the lithium battery protection. The output can be restored by pressing the BOOT button or charging the battery in one of the USB/SOLAR IN ports.
- If a 5W (or above) solar panel or USB charger is used, the CN3165 may run in full load, trying to charge the battery at maximum 900mA. In order to improve the cooling of the IC, it is highly recommended to attach the thermal conductive silicone pad and Aluminum cooling fin (included in the kit) to the bottom of the module where the label "Cooling Fin" is located.
