Interesting - can't seem to find anything similar in the US but didn't search that hard. I see it also has a CAN bus interface as well as the discrete inputs.
Do you send them the drawings and they program the small OLED or do you do it yourself from a computer?
It's a universal platform so they program the gauge scale and function (Tacho, speedo, etc), you are only limited by a 270 degree swipe. Than you tell them which data you want on the oled and the design of the gauge face. In my case I wrote a rather detailed specification with drawings, font sizes, control button functions, etc.
it's quite possible you can program it by yourself, I do not think its rocket science. I'll ask them to make sure.
