 ===== Overview =====
-The board holds all necessary components including surface mount shift registers (DOUT and DIN) on the backside and connects via a single 10pin cable to J2 on Wilba's control surface board. Additional modules (BPM and TPC displays) can be connected to a second 10pin connector that loops through all serial I/O signals from J8/J9 of the Core32/LPC17 board. The board features duo LEDs and the very nice {{:home:users:ilmenator:64250101_00_k.pdf|Marquardt 6425}} series of buttons with the {{:home:users:ilmenator:826000011_00_k.pdf|16mm square caps}}.

-The buttons do not align with Wilba's MB-SEQ frontpanel design. The reason for this is simple: In my front panel there is a TPD (Track Position Display), a step display, and a [[http://ucapps.de/midibox_seq/mbseq_v4_bpm_digits.pdf|BPM display]] to the left of the button / Duo-LED matrix. A second reason is that the protoboard manufacturer ([[http://www.goldphoenixpcb.com/|Gold Phoenix PCB]]) I used has a size limit that I had to respect.

 The total size of the PCB is 335.15mm x 97.92mm.
+===== PCB Layout v2.0 =====
+Meanwhile, I have created a version 2 of the board, which basically has all the features of the original one, plus it can hold three different types of switches:
+- the Marquardt 6425 series (my favourite switches)
+- ITT Schadow D6 series (TK's favourite switches)
+- E-Switch 612-TL1100 series (the ones that Wilba used on the SEQ v4 board).

+==== Where to buy? ====
+If you are interested in building 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 May 2022, I have PCBs available for 25€ each. I can also provide you with complete kits with Marquardt or D6 switches in black.
