Review on 🔍 Advanced SunFounder Mifare RC522 RFID Reader IC Card Proximity Module for Arduino - Enhanced Antenna RF Module for Efficient Card Reading by George Woods

This unit does not come with a pinout explanation and if you look at the reviews you will find 3 different pinout guides; because the company didn't even bother to offer a 2 x 3 inch piece of paper with an explanation of the pens. In addition, when you try to access their website, you get SSL errors, which are usually for beginners who do not know how to set up a website. FIND ANOTHER BRAND OF RFID READERS TO BUY!
