-===== Layout =====
+===== PCB =====
 As with any user interface board, form follows function here. Switches and encoder are mounted on the front, everything else sits on the back of the PCB. There are mounting holes all over the PCB, SW5 (on the lower left) doubles the encoder switch if needed, e.g. to act as a "fast" button.
+Jumper JP1 activates SW5, JP2 activates the encoder switch when closed. You can use both in parallel if you want to. Jumpers JP3 and JP4 determine the direction of the encoder. These have to be closed in one of the two possible configurations, otherwise the encoder will not be connected to P1.

 The total size of the PCB is 97mm x 49mm.
+==== Where to buy? ====
+If you are interested in buying this, send a personal message (PM) to user //ilmenator// over at the [[http://midibox.org/forums/|MIDIbox forum]] (you have to register to be able to send PM). As of August 2020, I have PCBs available for 4,50€ each.
+===== Switches =====
+At least three different switches can be used.
+==== Marquardt 6425 series ====

+===== Encoder =====
+I have chosen to follow the ALPS STEC11 type encoder pinout, as these seem to be pretty common, at least here in Europe. The data sheet is [[https://cdn-reichelt.de/documents/datenblatt/B400/STEC11B.pdf|here]]. The block of jumpers JP3 and JP4 must be closed in parallel, either horizontally or vertically, and determines the turning direction of the encoder. These jumpers basically exchange where the pins A and B of the encoder go to. The middle pin of the encoder has to be the common C pin.
