Openlog Data Logger


 OpenLog is an open source data logger

     The OpenLog is an open source data logger that works over a simple serial connection and supports microSD cards up to 64GB. The OpenLog can store or "log" huge amounts of serial data and act as a black box of sorts to store all the serial data that your project generates, for scientific or debugging purposes.
     The OpenLog runs off of an onboard ATmega328, running at 16MHz thanks to the onboard crystal.The OpenLog draws 6mA when recording a 512 byte buffer, but as that process takes a fraction of a second, the average current draw is closer to 5mA. Keep in mind though that if you are recording a constant data stream at 115200bps, you will approach that 6mA limit. All data logged by the OpenLog is stored on the microSD card that involve the features of 64MB to 64GB capacity and FAT16 or FAT32 file type.
Note: The latest version of the firmware (included with this board) does not compile in For Arduino 1.6.7. You will need to compile in 1.6.5.

Note: After powering on the memory card for the first time, the config.txt file will be generated on the memory card, which replaces the baud rate of the serial port. This parameter can be changed. Please change the serial port of the flying control or main circuit The baud rate is the same as the baud rate of the recorder.


  • VCC Input: 3.3V-12V (Recommended 3.3V-5V)
  • Log to low-cost microSD FAT16/32 cards up to 64GB
  • Simple command interface
  • Configurable baud rates (up to 115200bps)
  • UART serial interface
  • Preprogrammed ATmega328 5V 16mhz and bootloader
  • Four SPI pogo pins
  • Two LEDs indicate writing status
  • 2mA idle, 6mA at maximum recording rate
  • To ensure the operation of the minimum connection vcc, gnd, rx
  • Three modes: new, add, command
  • Change the tf card's config file on your computer (if it's a new card, insert the card for the first time after power-on, the config file will be created automatically) to change settings such as baud rate. You do not need to buy any specialized tools to change the serial settings to use your needs.
