Factory Setting: 115200bps
Working Voltage: Win Voltage (DC3.3v ± 10%)
Working Current: Less Than 100ma
RST: Reset the Module, and the Low Level is Valid (this Pin is Needed when Supplying Power to the Module Uninterruptedly, and It is Recommended to Hanging in the Air in Other Cases)
VIN: Fingerprint Module Main Power Supply, Default 3.3v
GND: Power Ground
RX/DP: Module Receiving Data Pin
TX/DN: Module Sending Data Pin
+3.3v: Power Supply of Finger Detection Function Circuit
Wakeup: Finger Detection Function Output Pin, Which Outputs High Level when a Finger is Pressed
The specific operations are as follows:
1. The+3.3V of the module shall be kept powered all the time and cannot be disconnected.
2.Low power consumption is required. Disconnect the VIN power supply. At this time, a finger contacts the glass of the fingerprint collector. The WKP pin of the module will output a high level, and then turn back to a low level.
3.After detecting the high level of WKP output, when the fingerprint module needs to work, turn on the VIN power, wait for 350ms, and then send a command to the module.
