The Logomatic v2 takes everything about multiple logging projects and boils it down to an easy to use device, that is now more adaptable than ever!
It's surprising how often we at Solarbotics have a project we want to sit in a window and do stuff... and measure how well it does it. Piece-mealing together data-acquisition units/loggers has become a whole lot easier with the SparkFun Logomatic v2!
The Logomatic version 2 incorporates the ARM 7 LPC2148 microcontroller with USB, battery charging, and microSD support. Woohoo!
The Logomatic v2 uses a USB mass storage stack to appear under any operating system as a regular, dumb-old flash drive. Logs are created in FAT16 format on the micro-SD 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 match those found on LiPoly batteries or other power sources up to 7.5VDC. If you choose to use LiPo batteries, the Logomatic v2 has a built-in charger to charge batteries off USB.
The Logomatic v2 ships with basic serial text and analog logging. Users can easily start with this firmware but are encouraged to modify the firmware for their specific requirements. It's a truly flexible logger.
