The Gravity: Serial Data Logger is an improvement on the old MicroSD Card Module as it allows for more convenient data storage and supports direct data printing through the serial port without the need for additional code. It features 128MB of onboard Flash memory, eliminating the need for a TF card. It also has a USB function, allowing you to connect it directly to a PC to read stored files without the use of a card reader. The onboard LED indicator allows you to easily monitor data writing status, and the SAVE key makes it easy to store data in separate files.
