Description
The Gravity: Serial Data Logger can store data conveniently and supports direct data printing through the serial port without additional code.
The Serial Data Logger provides an onboard 128MB Flash memory meaning no microSD card is required. The module comes with a USB-C function allowing you to directly connect it to a computer to read the stored files without the need for a card reader. The onboard LED indicator allows data writing status to be viewed visually, whilst the onboard Save key makes it easier to store data into separate files.
