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 adjustby Alhassan - RAMPS Electronics
