Logomatic v2 Serial SD Datalogger US$40.95

Logomatic v2 Serial SD Datalogger

The Logomatic Version 2 board incorporates the LPC2148 ARM7 core based microcontroller with USB, battery charging, and microSD support. The board comes pre-loaded with a USB bootloader for even easier and faster modification of the firmware. No programmer required!

This is an updated version of the Logomatic v2 which adds SDHC support for microSD cards larger than 2GB. Also, the USB connection is now micro-USB; the original Logomatic v2 used mini-USB.

The Logomatic v2 uses a USB mass storage stack to appear under any operating system as a flash drive. Logs are created in FAT32 format on the microSD media and can be downloaded quickly over a USB connection by dragging and dropping the text files from the device. The microSD card can also be removed and inserted into a card reader to download the logs.

The board comes with a JST connector to be powered from any of these LiPo Batteries or other power sources up to 7.5V DC (a barrel jack adapter is available in the options below). If you choose to use LiPo batteries, the Logomatic v2 has a built-in charger to charge batteries via USB.

The Logomatic v2 ships with basic serial text and analog logging. You can start with this firmware, or modify it for your specific requirements. It's truly a flexible logger.

Note: Your microSD card must be formatted with the FAT32 file system. In Windows XP, you can right-click on the card's drive letter and select Format, then open the File system menu in the dialog to select FAT32. In Windows 7, you must open a command prompt (click the Start button and type cmd in the search box, then start cmd.exe), and type format X: /fs:FAT32 where X is the SD card's drive letter note however that this command only supports cards up to 32GB. For larger cards, you'll need a third-party formatting tool.
