standard PC

The outer diameter of the wire is 1

This is 20-pin with 10 individual position slide type DIP switch

It has collector continuous current of 15A and a Collector-Emitter voltage of 230V

for that you need a reliable soldering kit which can be used easily to solder the components in place

EM-18 RFID Reader Module [C] NodeMCU/ESP standard PCRadio frequency Identification (RFID) is a wireless identification technology that uses radio waves to identify the presence of RFID tags. We need to bring the RFID tags near to the reader to read the unique identifier number associated with that RFID tag as it has a microchip with radio antenna mounted on a substrate which carries a unique 12 byte identifier. RFID Reader has a transceiver and antenna mounted on it to read the data of the RFID tag and
