Great Value Module

Compact and does exactly what it says. Soldering the headers was easy. Reading and writing speeds are decent for hobby projects.

Good but pins are tight

Functionality is perfect. My only minor complaint is the header pins were a bit tight to insert into my breadboard initially. Otherwise solid.

Works with ESP32

Connected this to an ESP32 dev kit. Make sure to use the 3.3V pin on the ESP32 side. Logging sensor data successfully.

Level Shifter is Key

I burned a previous card reader by connecting 5V directly. This module saves you from that mistake. Highly recommended for beginners.

Perfect for Data Logging

Used this with an Arduino Uno for a weather station. The level shifter makes it safe to use with 5V logic. Works flawlessly with the standard SD library.
