Installing NFC on electric vehicles

Overview

Electric vehicles are equipped with NFC. This integrated wide voltage transformer has an input voltage of DC8-120V and a dual output of 5V+3.3V 1.5A.

The buck circuit uses OC5806L chip

Input voltage DC8-120V, dual output 5V+3.3V 1.5A

The control center is esp8266,

The relay can control a maximum current of 10A.

Integrated buzzer to feedback card swiping results.

The nfc module is RC522. This board only has interfaces. You need to purchase the RC522 module separately.
