The FINGER Hat is a remarkable addition for the M5StickC. It's equipped with the 'FPC1020SC' fingerprint sensor, making fingerprint addition, verification, and management a breeze. With its compact design, serial protocol, and ultra - low power consumption, this M5 Unit is highly appealing. It offers fast fingerprint matching with top - notch security and maximum user convenience. You can program it to set custom fingerprint recognition comparison and security levels. Ideal for enhancing project security with biometrics. UART settings include a default baudrate of 19200bps, 1 start bit, 1 stop bit, and no parity. Key features are as follows: It can store 150 fingerprints, has a False Acceptance Rate of <0.001% at Security Level 3, and a False Rejection Rate of <0.1% at the same level. It supports comparison modes of 1:1 (Authentication) / 1:N (Identification), with a security level ranging from 1 - 5 (default 3). The quiescent current is <20μA, and fingerprint preprocessing takes less than 0.45s. It outputs user names, finger images, and feature values, with a characteristic value size of 193 Bytes. The communication interface is UART, supporting baudrates from 9600bps - 115200bps (default 19200bps). It operates in a temperature range of - 10°C - 60°C and humidity of 20% - 80%. The package includes 1x FINGER HAT. Applications include fingerprint attendance machines, passwordless authentication, and user identification.
Using the FINGER Hat with your M5StickC is easy. First, make sure the UART settings match your requirements. The default baudrate is 19200bps, but you can change it according to your needs. To add fingerprints, follow the programming instructions to set up the device. When verifying fingerprints, the hat will quickly match them with the stored ones. Remember to keep the sensor clean and dry. Avoid exposing it to extreme temperatures outside the - 10°C - 60°C range or high humidity over 80%. If you need to change the security or comparison levels, you can program the M5 Unit as per your preference. This will help you get the best performance and security for your projects.
