QUICK START GUIDE
The output voltage on this board is preset to 4.2V (for a single cell battery). The board layout
accommodates most commonly used capacitors.
The LEDs are power indicators. When LED1 is on, the 5V input is present (LED1 is off when the input
is disconnected). When LED2 is on, the battery is charging, and when the battery is full or there is no
battery connected, LED 2 will turn off.
1. Set the charge current I
