DFRobot 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 a serial port without additional codes.

The Serial Data Logger provides onboard 128MB Flash memory, no more TF card is 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.
