Schematic diagram of the fingerprint module circuit board:

Mostly only terminals 1 to 4 are used, and I do not need the rest of the terminals, except in some applications

If you use DC3.3V power supply, short circuit as shown below, but you need to be careful, if the power supply is wrong, the module will burn immediately!
