Schematics for UltiPanel with rotary encoder
Description
Because you want to have different interconnection for non-Ultimakers, my current board file is not very useful for other printers.
In this video first seconds, you can see the thing in an laser cut enclosure: youtube.com/watch?v=MTuq1QIE9TE
Instructions
* HRS 163 reverse Type normal size SD Card.
* EC11E15244B2 alps encoder
* A 4050 level shifter: 74HC4050D
* A 20x4 LCD with backlight
* R_LED depends on your LCD, some have a resistor soldered onboard to have the backlight working with 5V out of the box .
GPIO Pins you need:
* 3 for the encoder
* 6 for the LCD
* 1 for the Piezo
* 5 for the SD card (fixed pins: MOSI, MISO, SS, SCK; free pins: card detect)
Voltages: 3.3 (low current), 5V (large current for backlight), GND
It probably would work on most arduino mega based RepRap PCBs.

good morning.
I have to tell, that the you construe control is really nice.
I'd like him too built.
Might I ask for transmission PCB to format .brd ??
Well please
would there be anyway to combine this with the serial lcd board, like let it handle all the stuff and pass it over a serial pin (think we need only one pair then) some electronics seem like they have very little in the amount of availible pins? Would be cool and a power upgrade to this whole design :-D :-D ;)

my first design (thats the 4th version) had a dedicated microcontroller onboard, to communicate with the lcd, and gather the encoder pos. However, its quite impracital: You then have two firmwares, if you don't waste an arduino there, you need to program a bootloader, then you need a additional communication protocol between the two microcontrollers. Keep it simple was the idea, so the microcontroller was thrown out.
The second design had a parallel shift register to gather all the switch states (originally, there were 8 buttons). Well, maly people did not like the "design" and basically begged me to use a click encoder and a very simple menu structure.
I think the result is good as it is, because its quite easy to add the functionalyity. About the pins: Well, if you have a setup with few pins, also the microcontroller is probably low in memory/program space. I am absolutly not sure if it can handle all the size of the LCD code in marlin.
i love this idea.
any news on when or if it will be available.
i think there are many person who would like a board or a kit
Any idea yet as to when this might be available for purchase through the Ultimaker store ?
Am I right in thinking that if the mainboard doesn't have 3.3v this will need to have a 3.3v regulator onboard?
Could you post the board files too? Or the dxf you used to mill it?
We do have a few Ultimakers ;)

For those of you that want to build the board, I found the files at:

I have no idea how current they are and haven't built it yet, but am planning to cut it on my CNC machine on the next week or so. I wouldn't mind buying one from Ultimaker, but I can't get past paying $58 for shipping.
