Frequently asked questions
Which battery can I use with this module?
It is designed for a single 3.7 V Li-ion or Li-Po cell. Connect the cell with the correct polarity, as reverse polarity can damage the board.
Can it power a 5 V device directly?
The module provides a regulated 5 V output through its boost stage. Check that your device's current draw is within the module's output capability, since the listing does not state a maximum output current.
