## Customer Reviews

### ⭐⭐⭐⭐⭐ Working as expected
*by A***M on August 28, 2025*

Bought 4, got them working quickly just googling drivers, had to use a meter to confirm a few pin assignments but everything works as expected. Have read i2C sensors and drawn on SPI displays with no problems!

### ⭐ Driver Installation Does Not Work
*by C***N on April 8, 2023*

Documentation is sparse, and it does not include the driver installation. I downloaded everything but the documentation does not offer anything new that is already on the web page. After driver installation, Windows 11 still shows "Unknown Device" in the device manager.

### ⭐ USB drivers do not work
*by J***S on August 26, 2023*

USB drivers do not work.
