So I’m trying to learn about how the ESP8266 works so that I can finish a project I’m working on. I however am very new to this and don’t know very much. I am just trying to wire my 8266 to a RFID reader.
First, can I just use jumper wire like used for breadboards and connect a female header to the bottom pins then strip the other end and connect/crimp it to the rfid reader?
Also, is it fine for the entire 9V to pass into the 8266 or should I just run it straight into the rfid reader then use some other power source for the 8266? This is assuming it’s portable and not connected to my computer.
Any help with this would be greatly appreciated, thank you!
