Overview:
1. R301T capacitive fingerprint module adopts imported capacitor small-surface acquisition chip, integrated fingerprint algorithm chip, with fingerprint input, image processing, feature extraction, template generation, template storage, fingerprint comparison (1:1) or fingerprint search (1) :N) and other functions, suitable for fingerprint locks, fingerprint safes, fingerprint access control and other occasions.
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 MCU and powers up the fingerprint module, thus saving power. the goal of.
3.R301T can be used together with K200,K212,K215,K216 fingerprint control board.

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.
Package Included:
1 x R301T fingerprint module
1 x 6 core connection short line
