4. What is Arduino®
Arduino®is an open-source prototyping platform based in easy-to-use hardware and software. Arduino®boards
are able to read inputs –light-on sensor, a finger on a button or a Twitter message –and turn it into an output
–activating of a motor, turning on an LED, publishing something online. You can tell your board what to do by
sending a set of instructions to the microcontroller on the board. To do so, you use the Arduino programming
language (based on Wiring) and the Arduino®software IDE (based on Processing).

5. Overview
This NFC/RFID controller shield is based on the PN532 chip and can be used for field communication close to
13.56 MHz. This shield comes with an on-board antenna. It is compatible with SPI, IIC, UART interface to
communicate and needs to be stacked directly onto the VMA100 UNO control board.

6. Connections
The VMA211 RFID/NFC reader contains an on-board antenna, but for easy mounting reasons, an additional
antenna is included in the VMA211 set. The used antenna can be selected by two jumpers on the VMA211
board.
ATTENTION! Do not operate the VMA211 without these jumpers.

7. Switch Settings
The two switches on the VMA211 allow you to change the communication mode. By default, they are set for
SPI.

8. Example
Plug the VMA211 into the VMA100 (UNO) board, and connect the unit to your computer.
Download the example code and libraries from our website (VMA211_example, PN532_SPI and SPI).
Open the Arduino®IDE, open the VMA211_example (after extraction from Zip) and add both ZIP libraries.
Compile and upload the code.

When uploading is finished, start the serial monitor.
The VMA211 will send you a hello message.
Bring your NFC/RFID tag or card close to the selected antenna. You can read the information in the serial
monitor.
