RFID2

SKU:U031-B

Description

RFID2 is a radio frequency identification unit. Built-in WS1850S chip, working frequency is 13.56MHz. Supports reading card, writing card, recognition, recording, and encoding RF card Multiple functions such as authorization and authorization. Use magnetic field induction technology to realize non-contact two-way information interaction, read and verify the information of proximity cards. It can be used in access control systems, check-in systems, warehouse goods entry and storage, and community vehicle entry and exit registration needs Application scenarios for information verification.

RFID2 compared to the previous generation RFID UNIT only makes the replacement of read and write IC (RC522->WS1850S), there is no difference in function.

EasyLoader

Click to download EasyLoader

1.EasyLoader is a simple and fast program burner. The EasyLoader in each product page provides a product-related case program, which can be burned to the main control through simple steps, and a series of functional verifications can be carried out .

After downloading the software, double-click to run the application, connect the M5 device to the computer through the data cable, select the port parameters, and click "Burn" to start burning. (When burning for M5StickC, please Set the baud rate to 750,000 or 115200)

At present, EasyLoader is only applicable to Windows operating system, compatible with M5 system and uses ESP32 as the control core host. You need to install the CP210X driver before burning for M5Core (if you use M5StickC as the controller, you don’t need to install it) [click here to view Driver installation tutorial](/en/related_documents/M5Burner#Install the serial port driver)
