FAQ
Answer:
The WAKE pin is a wake-up pin, which only works when the RST pin is low and the module goes into sleep mode. The fingerprint metal shell outputs a high level after detecting the finger and returns to a low level when the finger is released.

Answer:
After the finger presses the fingerprint module, the level of the WAKE pin will change. The MCU recognizes this level and sends relevant commands to control the fingerprint module.
