Finger is a fingerprint sensor that makes fingerprint verification super simple.
The Uart protocol, compact size and ultra low power consumption make the use of MSStack series products very attractive. It performs fast fingerprint matching with the highest level of security and the ideal convenience of the user. You can program to set the level of comparison of the fingerprint recognition and the different security level. If you've ever thought about protecting your project with biometrics, don't forget to include this MSunit Finger.
This unit communicates with the M5Core by UART protocol connected via PORTC.
The MAX30100 is a complete solution of Pulse Oximetry System and Heart Rate Sensor. The MAX30100 provides a very small solution without sacrificing optical or electrical performance.
This LED Matrix 24 × 8 display is specially designed for the FireBeetle series. It supports low power mode and scroll display. With HT1632C high-performance LED driver chip , each led has an independent register, which facilitates separate driving. Integrates a 256KHz RC clock, only 5uA in low power mode, supports 16-scale PWM brightness adjustment. This product also works with another Arduino microcontroller like Arduino UNO (same as DFRduino UNO).
Electrolytic Condenser for use in rectifier circuits, power supplies and general electronic circuits. When connecting the Electrolytic Condenser, check the polarity of the terminals to prevent component damage. The larger terminal corresponds to the positive, and the smallest to the negative.
