   1. CR95HF Easy Overview

    CR95HF Easy is a RFID application development board designed and manufactured by AT-COM that allows users to add their RFID applications. Board integrated transceiver chip CR95HF 13.56MHz frequency and antenna design directly on the PCB, supports ISO / IEC 14443 Type A / B, ISO / IEC 15693 and ISO / IEC 18092. CR95HF Easy communication with Microcontrollers through UART interface (TXD, RXD) and SPI interface (MISO, MOSI, SCK, CS) on the ATCBus header. The board is designed with a 3.3V power supply, with a power LED, operating with a RFID tag or a 13.56MHz identity card. Ideal for protection or tracking systems that need RFID support. CR95HF Easy offers an entirely new design style, experience the great "Plug and Play" feature with AT-COM's Easy Boards.

    3. Features of CR95HF Easy

•  CR95HF-VMD5T chip operates at a voltage range of 2.7-5.5V. With CR95HF Easy product, the chip is designed to run at 3.3V voltage. Power supply for the board is provided from the pins 3V3, GND on the ATCBus header.

• The board supports ISO / IEC 14443 type A / B, ISO / IEC 15693 and ISO / IEC 18092.

• Antennas are designed directly on the PCB, stable transceiver capacity, 

       - For the tags according to ISO/IEC 14443, the actual tags identification distance is 3 cm.

       - For the tags according to ISO/IEC15693, the actual tags identification distance is 4.5 cm.

• The board supports serial communication through UART interface (TXD, RXD) or SPI interface (SDI, SDO, CLK, CS), users can select by welding 3 pins select on the board as follows:

          - Location A: choose to communicate via SPI (default position when produced). 
          - Location B: choose to communicate via UART.

• CR95HF Easy can be combined with other Easy boards that implement RFID applications and solutions:

        - Managing employees into the office.

        - Driver management in the transport, taxi, combined with vehicle cruise control.

        - Managing pupils, students in schools.

        - Managing materials, components in stock.

        - Sales manager, instead of barcode scanning tool.

• In addition, other applications users can contact AT-COM for advice and design assistance.
