Rfid Unit (MFRC522) - M5Stack Rdif

The M5Stick-C is an ESP5 powered M5Stack mini. It's a portable, easy-to-use, open source IoT development board.

This is an IoT Experiences Kit, developed with MSStack, It is a complete learning table with ESP32 technology, which includes everything you can imagine in industrial IoT + application scenarios. You will be able to do experiments such as: robotic movements, the most used serial communication port (RS485 RS232), relay control, all different types of button control, RF reader, speaker, microphone etc ... all programmed through the kit M5Stack base. Programming can be done through Blockly (UIFlow), Arduino and Micropython.

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 is designed with an N20 Engine and includes small propellers. This N20 motor has a supply voltage of 5V. And it has a rotation speed of 8800RPM.

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.

Angle is a 10K potentiometer that can be used for continuous control, such as volume, brightness or engine speed. A potentiometer is a manually adjustable variable resistance with three terminals. Two terminals are connected to a resistive element, the third terminal is connected to an adjustable cleaner. The position of the wiper determines the output voltage. The output voltage is captured and converted by AD in ESP32 on portB.

This is a wireless communication module, integrated with the M8321 NB-IoT module, which provides TD-LTE / FDD-LTE / WCDMA / TD-SCDMA / GSM / GPRS / EDGE frequency band and LCC + LGA package type. It integrated abundant Internet protocols, standard field interface and functions, supported WindowsXP, Windows7, Windows8, Windows10, Linux and Android USB driver.

In the layout of the LTE-4G module, more hardware resources were added, reserved lanes for speakers, 3 LEDs, USB interface, double antenna allowed.

Relay, as its name implies, implements a relay function. The relay can be used as a switch operated electrically through the coil to mechanically operate a switch, where it is sometimes necessary to control a circuit of another voltage and current load through a separate low power signal, such as a digital signal emitted by a mircoprocessor. Up to 30V DC and 220V AC.

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 Plus is an enhanced M5 Module that comes with Lipo battery (500mAh), gear potentiometer, IR transmitter, port PORT B (GPIO port) extended, port C (UART port) of the MS core and a microphone solder block. Equipped with MEGA328, it can be a major upgrade of hardware resources, adding PLUS to your work.

Communication Protocol: IIC (0x62).

It is a Kit with 6 Internal M5 Units (ENV, IR, RGB, PIR, ANGLE, HUB). Like another M5Stack Development Kit, MSGO is powered by ESP32.

Every M5stack development kit can be programmed using Arduino IDE, WebIDE UlFlow, Micropython and Blockly, simplifying the development process for those who require a joint hardware and software solution, M5stack not only has wide-reaching IoT applications on industry, at home, but also enables students to learn to code.

IR is an Infrared Photoelectric Sensor. The infrared remote control is widely used in consumer electronics; it can be used to operate devices such as televisions, DVD players or other household appliances within a short distance. Since this unit comes with a transmitter and receiver, you can practice not only IR encoding, but also IR decoding.
