Ramp1.4 + RFID ?
November 11, 2020 02:30PM
hello guys I am working on a storage system using ramps 1.4 so far everything going well

but now I want to add RFID to the project
since RFID RC522 require SCK, MISO, and MOSI and they are already there in ramps 1.4
but now my problem is 3.3v output, SDA, and the RST I don't know where should I put them, and especially for the 3.3 v is there any way to connect it without any circuit adjusting
