The TickTag GPS logger is micro-sized below 1g, but still collects thousands of GPS fixes. You access it via a simple smartphone user interface.  The TickTag bridges a technological gap in wildlife ecology. Finally, perform high-resolution studies with small animals.  Or, scale-up your studies and make it a ‘wearable’ for larger animals. 


TickTags connect to the user interface breakout board (UIB) as the smartphone link for data download and system configuration.
