Interface Details 

Pin No. Signal name Signal Description
PIN 1 Touch Power 3.3V Touch sense function need to supply power separately (It is better the power can be controlled). Power: DC3.3V± 0.1V   Current:1.5uA to 2.5uA
PIN 2 Finger Detect Output high level when detected finger, and output     low level once finger left
PIN 3 UART-TX Module Transmit Output,3.3V TTL Logic
PIN 4 UART-RX Module Receive Input,3.3V TTL Logic
PIN 6 VIN DC Input, Range of Voltage is 3.3V±10%
PIN 7 FP Reset Reset at low level (reset time>100ms), Work at high level. After Reset, it will cost about 350-400ms for system initializing andprograms loading; Only after that the module can communicate with MCU by UART

FAQs About CAMA-SM50 Embedded Optical Fingerprint Module

1. Does the SM50 embedded optical fingerprint module support Windows, Android or Linux system?
    Answer:  Yes, SM50 embedded optical fingerprint module can workd with these operating system. 
Actually SM50 embedded optical fingerprint module is an OEM optical fingerprint module, with our
command protocols, it can work with any operating system.

2. Does the SM50 embedded optical fingerprint module support read and write fingerprint template ?
    Answer:  Yes, SM50 embedded optical fingerprint module support read and wrtie fingerprint template .
If you need, you can extract the fingerprint templates from SM50 by the read template command and
wrtie fingerprint template into the SM50 from other place by write template command. 

3. Does the SM50 embedded optical fingerprint module's template data compatible with other
manufacturer's fingerprint template data?

    Answer: No.  SM50 embedded optical fingerprint module support CAMABIO fingerprint template format
only, it do not compatible with other manufacturer's fingerprint template format.
