Features:

  • The module (MicroSD Card Adapter) is a Micro SD card reader module for reading and writing through the file system and the SPI interface driver.
  • SCM system can be completed within a file MicroSD card .Support Micro SD Card, Micro SDHC card (high speed card).
  • 3.3V regulator circuit: LDO regulator output 3.3V for level conversion chip, Micro SD card supply.
  • Level conversion circuit: Micro SD card to signal the direction of converts 3.3V, MicroSD card interface to control the direction of the MISO signal is also converted to 3.3V, general AVR microcontroller systems can read the signal.
  • Positioning holes: 4 M2 screws positioning holes with a diameter of 2.2mm, so the module is easy to install positioning, to achieve inter-module combination.
Works as expected

These are good for experimental data logging at a reasonable price. Once I got my Arduino NANO sketch operational, they have worked flawlessly. Please note, they do not come with any documentation.

Works great

It works great for what I needed it for. Looking rpm and map data on a motorcycle with Arduino is a snap with this

It works !

It does what its supposed to do and seems to be well constructed. I would buy it again.

Works well to add sdcard reader support to 3D printer

I put this in my MKS Gen L based printer, so that it could store printer files in a local buffer. It worked well and was easy to install into an auxiliary port.

Crazy good value

I needed to create a few data loggers that need to be dispersed in my lab (not, like, an evil genius lab, but a normal testing lab) and these things work great. What can I say? They work out of the box and the HiLetgo quality seems to be getting better. The only ding, and it's very small, is the pin position. No biggie, de-solder and put my own in. For the price, totally worth it.

Great value for money

Not much to say. They arrived as advertised and there weren't any issues with them so far. they have voltage regulators on the board, so you can use them with 5 volts. Would get again! :D

Excelente la tarjeta SD

Funcionan muy bien. Llegaron muy rápido.
