A and B both are the power input(VIN/VOUT is positive, GND is negative).
C is regulated voltage output for 5V( label 5V is positive, GND is negative, which can output 4 channels power at the same time).
Solder A & C in B, you can adjustable voltage output for 10V-20V(label 10V is positive, GND is negative, which can output 4 channels power at the same time).
the power output, it is to connect ESC or other equipments, each solderred pad has the screen printing label “ +/- ”,  label “ + ” is positive, label “ - ” is negative.
Note: The LED of the main board need to be supported by module 5V, it will be lit after finished assembled.
