It’s long time we planning to make an easy to use yet powerful data logger, either logging some cycling or in the name of new product line.

For mobilily, it has to be small enough for pocket size, water proof and rugged.

For easy usage, on board RTC is good as well as a SD card.

Then, why not some extensibility and flexibility? Yes, now it reserves full arduino pin header, not only be used as a stand alone datalogger, but also stack on another Arduino as a shield to form dual- core system.

Attaching Diagram and application ideas.

A photo of the prototype, final version will separate the GPS module part.

Suggestions welcomed! It will be ready to stock very soon. 🙂
