RDM6300 RDM630 RFID Reader with ESP8266 NodeMCU
In this tutorial, we will learn how to interface RFID reader RDM6300 or RDM630 with ESP8266 NodeMCU. Both of these RFID readers communicate via a serial connection on UART and follow the same interfacing with ESP8266 thus this tutorial will be compatible with both types of RFID readers. First, we will give you a brief … Read more
