Smart Adapter
Based on bkubicek idea here on the forum, we realized this device.
Description
This RepRap Panel contains a SD-Card reader, an ALPS rotary encoder and a LCD with 4 rows. The electronic is safe of false wiring this adapter to your 1.3 or 1.4 RAMPS.
After connecting this panel to your RAMPS you are free of any USB cables, so the Smart Adapter supplies also power for your SD card. Further more all actions like calibration, axes movements can be done by just using the included knob on the Smart Adapter. Also you are now free to print your 3D designs without any PC, just with a g-code stored design on the SD card.
Schematics
As firmware we used Marlins' sources, to update the firmware in the future you just need an Arduino board, so you are good to go ;)
