-== The Buttons ==
+To make a small and easy to connect matrix over a hole Frontplatte is no fun. Thats why i made myself a better solution. Based on the common DOUT modules it can be connected to 3 SRs.
-I thaught a long time about how to make a Button PCB that does not explode in material cost.
-The best solution was to buy rubberbuttons from Sparkfun and cut them because the with of Fadercore is fixed by the minimal width of 8 Oleds side by side... 220mm in width / 8 makes a 27.5mm grid. What a pity that the Sparkfun pads are premade with a 25mm grid...
-you will need two of them:

 ==== How to get Started ====
-If its your first SMD soldering you can follow this on t1:58 : http://www.youtube.com/watch?v=5uiroWBkdFY
+The LEDs are mounted to the Edge of the Meterboard to get a very slim form. That makes it a bit harder to solder them but i guess that no one wont be able to do it.
-I recommend to not buy solder paste, instead buy some flux-paste like this on Mouser: 590-8341-10ML
+To solder the Header to the Edge there is a wite triangle printed to the PCB on one side. This Triange has to match with the Triangle on the Header.
 ==== Prepare the PCB ====
-Start with the SMD parts and then go on the the conventional parts also on the Bottom side.
+Well you should now by now how to solder Headers... :-)
-Then go on with the Topside and the LEDs.
-Check the Connections with a Lens.
 ==== Prepare the Connection ====
-Connect the core on J8/9 to J1 of the VLR-3x8But board.
+Connect the SEL, Row1-8 & Row9-16 with each a DOUT Header.
 ==== Test it in MIOS ====
