The RS232-B1 v2 is a low cost full RFID/NFC read/write device with RS232 interface that can operate in “host” connected mode or “stand-alone” mode. Supports MIFARE Classic® 1K, MIFARE Classic® 4K, NTAG2xx® and MIFARE Ultralight®. Additionally, you can read serial numbers from MIFARE Plus®, MIFARE® DESFire® and any transponder compatible with the ISO14443A standard. The RS232-B1 is based on our RFID-B1 module but is equipped with an additional integral antenna, an LED for tag in the field indication/ interrupt, mounting holes and flexible plated connection holes.
The RS232-B1 is an ideal choice if the user wishes to add RFID capability to their design quickly and easily. This device enables high performance RFID solutions to be devloped without the requirement of any RFID expert knowledge on the part of the user. This applies ideally for designs based on connection to a host microcontroller.
Furthermore, a wide range of peripherals is available on the module, such as a comparator, DAC/PWM and digital IO. These can be configured and accessed by specific commands and control registers.
The interface protocol can be found in the RFID B1 user manual.
