Gravity: Serial Data Logger for Arduino

Compared to the old MicroSD Card Module, this Gravity: Serial Data Logger can store data more conveniently, and supports direct data printing through serial port without additional codes.

The Serial Data Logger provides onboard 128MB Flash memory, no more TF card required. It comes with a USB function, which means you can directly connect it to a PC computer to read the stored files without using a card reader. Meanwhile, with the onboard LED indicator, data writing status can be viewed visually. And the onboard SAVE key makes it easier to store data into separate files.
