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.
