Description:
The working PMU (Power Manage Unit)can be only worked for charging mode or step-up mode at the same time.
If
the USB-A interface without any external load (like Pi), with 5V input
voltage of Micro USB, then the PMU enter charging mode. The PMU will
integrate a current-limiting resistor with the external voltage, 5V
voltage for Lithium battery, around 4.6V-4.7V voltage for USB-A
interface.(The "ON" LED lights )
The PMU would enter step-up mode
without external 5V voltage. Under this circumstance, turn on the
switch, USB-A interface can output maxmum 5V voltage, two USB-A
interface can maxmum output 1.8A current. The PMU itself has
current-limiting protection. it will be short circuit when over 1.9A
current
Packing Included:
1 X Lithium Battery Expansion Board
