What is Arduino®
Arduino®is an open-source prototyping platform based on 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). Additional
shields/modules/components are required for reading a twitter message or publishing
online. Surf to www.arduino.cc for more information.
Product overview
A dedicated and well-designed data logging shield for Arduino®.
The SD card interface works with FAT16 or FAT32 formatted cards. The 3.3 V level shifter
circuitry prevents damage to your SD card.
The real-time clock (RTC) keeps the time going even when the Arduino®is unplugged. The
battery back-up lasts for years.
Works with Arduino®Uno, Leonardo or ADK/Mega R3 or higher. ADK/Mega R2 or lower are not
supported.
Specifications
•back-up battery: 1 x CR1220 battery (incl.)
•dimensions: 43 x 17 x 9 mm
Testing
1. Plug your data logging shield into your Arduino®Uno compatible board (e.g. WPB100).
2. Insert a formatted SD card (FAT16 or FAT32) into the slot.
Testing the SD Card
1. In the Arduino®IDE, open the sample sketch [Cardinfo].

2. Your data logging shield uses chipSelect 10 instead of chipSelect 4. Change line 36 in the
sketch to:
const int chipSelect = 10;
IMPORTANT
The ATmega2560-based MEGA compatible (e.g. WPB101) and ATmega32u4-based Leonardo
compatible (e.g. WPB103) development boards do not use the same hardware SPI pin-out. If
you are using one of these boards, please specify the pins used for SPI communication with
the SD card. For the VMA202, these are pins 10, 11, 12 and 13.
In the CardInfo sketch, modify line:
while (!card.init(SPI_HALF_SPEED, chipSelect)) {
to:
while (!card.init(SPI_HALF_SPEED,1,11,12,13)) {

Also, an updated SD library is needed to avoid error messages. How to replace the SD library:
1. Download the updated SD library from the products page on www.velleman.eu. Make
sure the Arduino®IDE is not running.
2. Go to C:\Program Files\Arduino and create a new map, e.g. SD Backup.
3. Go to C:\Program Files\Arduino\libraries\SD and move all files and maps to your newly
created map.
4. Extract the downloaded SD library into the now empty SD map. Make sure that the .h and
.cpp files are directly under C:\Program Files\Arduino\libraries\SD.
5. Start the Arduino®IDE.
Testing the RTC (Real-Time Clock)
1. Download the RTClib.zip file from the products page on www.velleman.eu.
2. In the Arduino®IDE select Sketch →Include Library →Add .ZIP Library… Select the
RTClib.zip file you downloaded.
