Features:

  • OpenLog open source data logger
  • Supports microSD cards up to 32GB
  • Can log serial data on a serial bus to store all the serial data that your project generates
  • Useful for scientific or debugging purposes.
  • Uses an ATmega328 running at 16MHz
  • Draws approximately 2-3mA in idle (nothing to record) mode
  • During a full record OpenLog can draw 10 to 20mA depending on the microSD card being used.
  • All data logged by the OpenLog is stored on the microSD card.
  • Any 512MB to 32GB microSD card should work.
  • OpenLog supports both FAT16 and FAT32 SD formats.

Specifications:

  • Power Supply Voltage: 3.3V-12V (Recommended 3.3V-5V)
  • Simple command interface
  • Configurable baud rates (up to 115200bps)
  • Preprogrammed ATmega328 and bootloader
  • Four SPI pogo pins
  • Two LEDs indicate writing status
  • Current: 2mA idle, 6mA at maximum recording rate
  • Logic Level: 3.3V / 5V
  • Supports Micro SD cards and Micro SDHC high-speed FAT16/32 cards up to 32GB
  • Communication Protocol: SPI and FTDI (SPI for reprogramming the Atmega328 bootloader and FTDI for data transmission)
  • Primary interface: FTDI that can be connected directly to an Arduino to send data over a serial connection to the OpenLog
  • Micro SD card port on board
  • RXI Input: 2.0V-3.8V
  • TXO Output: 3.3V
  • 2 Status LEDs:
    • Right LED: Indicator LED toggles on/off when a new character is received. This LED blinks when Serial communication is functioning.
    • Left LED - LED blinks when the SPI interface for loading the Atmega382 bootloader is active. You will see it flash when the OpenLog records 512 bytes to the microSD card.
  • Pinout:
    • BLK: Ground 0V
    • GND: Ground 0V
    • VCC: 3.3V-12V (Recommended 3.3V-5V)
    • TXO: Transmit Output
    • RXI: Receive Input
    • GRN: Data Reset
