The R501 capacitive fingerprint module uses a capacitive surface acquisition chip and integrates a fingerprint algorithm chip with fingerprint entry, image processing, feature extraction, template generation, template storage, fingerprint comparison (1:1) or fingerprint search (1:N). Features.
Products include: R501 fingerprint module, 6 core connection short line, iron piece, screw 2
In battery-powered applications, the touch-sensing power supply is DC3.3V-5V, and the current is about 5uA. It must be always powered. When there is a finger, it senses a low level, wakes up the microcontroller and powers up the fingerprint module, thus achieving power saving. .
Module indicator description:
When the fingerprint command is sent to the module, the blue light is on, and the acquisition command is continuously sent. The blue light is similar to long light.
Fingerprint entry succeeds or compares, blue light flashes
Fingerprint entry or comparison failed, the red light flashes.
R501 shell is zinc alloy, with MICRO USB external power interface, external power supply can be used to charge treasure
