FingerPrint pin Full Details

Finger print processing components and fingerprint collection components are integrated in the same module. The size is small. And there are only 4 wires connecting with circuit, much easier for installation and use.

                  Working
Module waits for command from HOST after it is powered on. Module will respond by a Rx correct packet after receiving the correct command. Module will perform operations according to the command and will return corresponding information after the operation is successful. When the Module is performing operation, it will not respond to other command given by HOST. If the check sum for the received command is wrong, the module will send back receive error response.

  • Module receive correct Data:  0x4D + 0x58 + 0x30 + 0x01 + 0x01 + 0xD7
  • Module receive error Data:      0x4D + 0x58 + 0x30 + 0x01 + 0x02 + 0xD8
