M5Stack RFID 2 Unit WS1850S

The RFID2 Unit operates in the 13.56 MHz frequency band and uses the modulation and demodulation principle to interact with an RFID card. With this unit, the function of the card reader and writer can be realized. With this RFID Unit, you can create applications such as access control systems, time recording, warehouse management, and shared vehicle access recording. Connect this unit to the GROVE PORTA on M5Core or M5Stick. The i2C address is 0x28.

Info: Compared to the previous generation RFID UNIT, only the read and write IC RC522 was replaced with the WS1850S in RFID2. There are no differences in function.
