RFID has an RFID chip MFRC522 inside.
The MFRC522 operates in the 13.56MHz frequency band and uses the modulation and demodulation principle to interact with the proximity RF card. This unit can realize the function of the card reading and writing device, to identify and record multiple card information, to encode and authority a RF card.
It is able tp establish applications such as access control system, punching system, warehouse goods storage and community vehicle access registration.
Connect this Unit to GROVE PORTA on M5Core, IIC adress is 0x28.
all parts are fine thx , and all times again
RFID module tested with Core, Core Fire and Stick-C without problems (nevertheless it does not work if plugged thru Pa.Hub, which is obviously an Pa.Hub problem).
M5Stack and M5Stick are my favorite development tools. Easy to handle and everything in a box. The MFRC522 worked "out of the box". The available libraries and examples are helpful and well organized...
Exactly what I was looking for!
M5 stack turned on without a problem out of the box but when plugged into device, stopped powering on again, emailed support week ago with no response. Documentation is lacking on how to fix.
