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.

This module has two buttons of different colors. They share exactly the same mechanism, the status of the button can be detected by the status of the input pin, just capture the high / low electrical level.
This unit communicates with the M5Core through the Grove B port.
The Joystick is very similar to the 'analog' joystick on PS2 controllers (PlayStation 2). The X and Y axes are two 10k potentiometers that control 2D movement, generating analog signals. The joystick also has a button that can be used for special applications, so the entire unit can emit X-Y movement signals in both directions and in the Z direction.
This unit communicates with the MSCore via the GROVE A interface. The I2C address is 0x52, Reading the data transferred from the Joystick, you can obtain the movement information from the Joystick.
The MFRC522 operates in the frequency range of 13.56 MHz and uses the principle of modulation and demodulation to interact with the RF proximity card. This unit can perform the function of the card reading and writing device, to identify and record various information on the card, to encode and authorize an RF card.
The Earth Unit is a Sensor for measuring Humidity in Soil or Similar Materials. The Soil Moisture Sensor is quite simple to use. The two large stake-type sensors act as probes for the sensor, acting together as a variable resistance. The higher the moisture in the soil, the better the conductivity between the two, so that the sensor results in less resistance and higher GIS output.
You can read the moisture in the soil through ADC. Within this unit, there is an extra potentiometer to change the measurement range.
