Product Code: MIKROE-262

The RFid Reader Board has been designed for reading identification cards (RFid Cards) using radio waves. This accessory board comes equipped with a 125 KHz RF transmitter and receiver, and an EM4095 controller chip. While the included receiver/transmitter module with antenna and a 2x5 male connector allows the reader board to get connected with a microcontroller on the development system, EM409S is used for AM modulation/demodulation or as a driver for the antenna.

The RFid Reader Board works on the basis of amplitude modulation of radio waves and electromagnetic induction. Its primary functions are energizing, demodulation, and decoding. The board can be connected to microcontrollers or PC for encoding the data read from RFid tags. This signal is coded using standard Manchester coding. The additional board makes use of the provided antenna to receive data stored on the identification card (RFid Card). The reader is powered via a development system it is connected to. It comes fitted with a power supply LED indicator.
