VMA202 5. Overview VMA202 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, Duemilanove, Diecimila, Leonardo or ADK/Mega R3 or higher. ADK/Mega R2 or lower are not supported. back-up battery .........................
VMA202 IMPORTANT! The ATmega2560 (VMA101) and ATmega32u4 Leonardo (VMA103) 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 in order to avoid error messages.
