3.This SD Card module can make your SD application more easier and simple

4.Through programming, you can read and write to the SD card using your compatible for arduino

5.All SD SPI pins output, MOSI, SCK, MISO and CS

terminal of the charger using high voltage device

Built-in three-stage over-current detection circuit (over-current 1, over-current 2, or load short circuit)

MOS transistor can control the battery charge and discharge;

Adjustable voltage: adopt multi-turn precision adjustable potentiometer to adjust voltage.

Data storage: automatically save the state before the power failure, the output data will not be lost.

One key to turn off the output, and store the state before power off, no worry about data loss
