Logomatic v2 Serial SD Datalogger
The Logomatic v2 takes everything we learned with multiple logging projects over the years and boils it down to an easy to use device, that is now more adaptable than ever! Version 2 incorporates the LPC2148 with USB, battery charging, and microSD support. This allows us to use the SparkFun LPC2148 USB bootloader for even easier and faster modification of the firmware. No programmer required!
The Logomatic v2 uses a USB mass storage stack to appear under any operating system as a 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.
Board comes with a JST connector to be powered from our line-up of LiPo 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.
