Product Description SD Card Module Accessories Micro SD card module SPI interface mini TF card reader Baby Description: The module (MicroSD Card Adapter) is a Micro SD card reader module, through the file system and the SPI interface driver, SCM system to complete the file to read and write MicroSD card. Arduino users can directly use the Arduino IDE comes with an SD card to complete the library card initialization and read Module features are as follows: 1 Support Micro SD card, Micro SDHC card (high speed card) 2.-board level conversion circuit, namely the interface level for 5V or 3.3V 3 power supply is 4.5V ~ 5.5V, 3.3V voltage regulator circuit board The communication interface is a standard SPI interface 5.4 M2 screw positioning holes for easy installation Interface Description: Control Interface: A total of six pins (GND, VCC, MISO, MOSI, SCK, CS), GND to ground, VCC is the power supply, MISO, MOSI, SCK for SPI bus, CS is the chip select signal pin; 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;

this worked for me
I used it with an arduino

Works fine with Arduino Uno
Just tested it with the Cardinfo sketch. Works fine with Arduino Uno. However, when I tried it with a NodeMCU LUA, I had a problem. Anytime its MISO wire was attached to the nodeMCU, the MCU would stop working. Since the problem is probably with the NodeMCU and not the card reader, I am giving this 4 starts.

New defective board
First time I tried to insert a micro SD card it would only go about halfway into the slot. After a bunch of unusual wiggling and insertion attempts something seemed to pop loose inside the SD card slot and the card suddenly went in correctly. I was able to use the SD card OK as a data logger. I checked my data on a PC and it was recorded correctly. BUT... when I tried to reinstall the SD card into this board's card slot the card won't 'lock' into place. I carefully push it in and it springs right back out. My assumption is that I just happened to receive a 'new defective' board. Your luck may be better.

Works OK
This module works OK.I am using this with Arduino MKR 1400, so far I have had two problems with this module:1- every often it it can't read the card in it. the easy fix is to remove and re-insert the card.2- no matter if it is selected or not (via chip select), it consumes around 10 ml which for my project is not acceptable. I needed this module to use no energy when I go to sleep mode but it is not the case here.Generally I like it. however if you project needs to run on a battery, I wouldn't recommend this one unless you have a turn off switch of something.

WARNING: DO NOT PURCHASE THIS PRODUCT, IT IS A SCAM.
I have been trying for 6 hours to get this to work. 2 different arduinos. 2 different sd card libraries. Checked the wiring. tried different sd card formats. None of them work. I am returning this item as quickly as possible
