RFID Reader 125KHz with TTL Output

If you need an inexpensive way to get started with RFID, this is a great little module. Just power the module, and it will read any RFID card within range. It will output the cards ID in a serial string, which can easily be read by any microcontroller. The spacing on the pins is 2.54 mm, which means the module will directly fit on a breadboard. The EM-18 RFID Reader with TTL Output operating at 125kHz is an inexpensive solution for your RFID based application. The Reader module comes with an on-chip antenna and can be powered up with a 5V power supply. Power-up the module and connect the transmit pin of the module to recieve pin of your microcontroller. Show your card within the reading distance and the card number is thrown at the output. Optionally the module can be configured for also a weigand output.

EM-18 RFID Reader with TTL Output uses the EM18 RFID Module. It can be used to read our RFID cards. Using the board with micro controllers to read a card's data is very simple and required just a serial connection. The board should be powered at 5V, and it requires a direct connection to the micro controller's Serial Rx pin. The card data is transmitted over the serial line when the card is brought near the module.

The board has an on-board power indication LED, a LED and Buzzer to indicate the presence of a RFID Card. All the IO pins are brought out to standard clearly labelled header pins, which simplify prototyping time and effort. An output pin (DET) also indicates the presence of a RFID card. The board can also be used to output data in Wiegand format. It can detect cards in the range of 8-10 cm.
