Compared to the previous MicroSD Card Module, 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.
