Tutorial for GPS Logger


The GPS Logger is a light-weight device that records GPS signals within 1 meter of accuracy. It features an easy-to-use design and simple step-by-step instructions. Data can be accessed by downloading from the on-board micro-SD card, or by accessing a real-time web page on WiFi. Bright LEDs are used to indicate when the device is running, if it has a GPS lock, how strong the GPS signal is, and when it is recording.
