The board supports MIFARE and ICODE type tags and features an on-board antenna complete with tuning capacitor. The board features a buzzer which can be programmed to beep on the presence of a RFID tag as well as signals back to the microcontroller to detect when a valid tag is present.
To allow this E-Blocks 2 downstream board to work with a First Generation E-Blocks upstream board, you will need the BL0113 conversion board.
