SDLogger - Open Hardware Data Logger

SDLogger is a simple serial logger based on SparkFun/Nathan Seidle's OpenLog. It is using an ATmega644P processor running at 14.7456MHz and logs to full-size SD cards. It supports both standard SD cards (FAT16) and SDHC cards (FAT32). SDLogger ships with OpenLog firmware 1.61 installed (compiled with SDHC/FAT32 support and large 2048 character input buffer) together with an Arduino-compatible bootloader for easy program update.

Features

  • Simple to configure and use

  • Automatically logs data received on the serial input port

  • Can be configured using a config file on the SD card

  • Supports 2400, 4800, 9600, 19200, 38400, 57600, 115200 and 230400 serial baud rates at 8-N-1.

  • Supports both standard SD cards up to 2GB (FAT16) and SDHC cards up to 16GB (FAT32)

  • Large input buffer (2048 characters)

  • Full-size SD card form factor

  • 14.7456 MHz crystal oscillator for precise baud rate generation

  • Input voltage range: 3.3 to 12V

  • Arduino-compatible bootloader installed for easy program update

  • Full Arduino environment support - can be used as an inexpensive Arduino board for program development

  • I/O ports supported in Arduino environment (in addition to the main serial port): 4 analog inputs, second serial port, I2C port

  • Simple SDLogger original firmware restore procedure using the Arduino environment

  • SDLogger hardware/firmware designed by Saanlima/Magnus Karlsson and released under CC BY-SA v3 license

  • Design files, Arduino code and other ported code available on GitHub
