Power supply considerations
This board is powered through the USB 5V or with a 3.7V LiPo battery. When a USB port is connected, the battery management circuit directly supplies the card and start charging the battery. The charge status is indicated with three LEDs.
LED name | LED color | Description |
---|---|---|
low batt | red | battery level is low |
done | green | battery charging is done |
power | blue | USB power is present |
