## Description

Compared to the previous [MicroSD Card Module](https://www.dfrobot.com/product-875.html), this Fermion: Serial Data Logger **can store data more conveniently, and supports direct data printing through serial port without additional codes.**

The Serial Data Logger supports 32GB TF card, making it suitable for long-time data storage. It comes with a USB function, which means you can directly connect it to a PC 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 pin makes it easier to store data into separate files.
