Ramps-FD external EEPROM PCB wireless :)

Arduino DUE lacks EEPROM storage space. A compact circuit board offers a solution to this problem. Pinout from stepdriver is as follows: VCC GND SDA SCL No pull-up resistors are needed because the Arduino DUE board already has them in place. The same board can be ordered on Ali or Ebay, but it will require some wiring. My version is directly connected to Ramps-FD. The pin order on the RAMPS-FD board is: VCC GND SDA SCL Resistors that pull-up lines SDA and SCL are not needed because they already exist on Arduino DUE. A pre-made board can be purchased for 60 rubles on Ali or Ebay, but it will require additional wiring, which can be a hassle. My circuit is mounted directly onto Ramps-FD. The Dupont connector needs to be soldered to the PCB side, the contacts are removed and re-soldered, then the plastic cover is snapped into place.
