What interfaces does this module support and how should I connect it to a microcontroller or PC?
The module supports UART TTL logic level and USB 2.0 or USB 1.1. For PC use with RS232, a level converter such as MAX232 is required. The default UART baud rate is 57600 bps (9600 x N with N from 1 to 12). The TD pin connects to the host RXD and the RD pin connects to the host TXD.
What power and current requirements should I plan for?
Power supply is DC 3.6 to 6.0 volts or 3.3 volts. Typical current is under 120 milliampere with peak under 140 milliampere.
How fast is fingerprint processing and how much can be stored?
Fingerprint image time is less than one point zero seconds. Matching supports one to one and one to many. Storage capacity is up to two hundred templates with a 256 byte signature file and a 512 byte template file.
What security and accuracy specifications should I know?
The device uses five safety levels. False Accept Rate is less than zero point zero zero one percent at security level three and False Reject Rate is less than one point zero percent at security level three.
How is the PC communication configured and what are baud rate options?
The PC interface can be UART TTL or USB. The UART baud rate is 9600 x N bps with N from 1 to 12. The default N is 6 which equals 57600 bps.
