| - | 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 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.

| - | 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 TPC (Track Position Counter) 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 buttons do not align with Wilba's MB-SEQ frontpanel design.

| + | 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). | ||

| + | 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 June 2022, I have PCBs available for 25€ each. I can also provide you with complete kits with Marquardt or D6 switches in black. | ||

| - | And finally, this is how it looks like with the PCB mounted to the frontpanel using 8.5mm long M3 spacers (8mm spacer and a 0.5mm thick washer). The front panel is made from 3mm thick acrylic and the buttons are sitting flush inside the frontpanel. This way it is easy to slide across the panel to activate neighboring buttons. | + | And finally, this is how it looks like with the PCB mounted to the frontpanel using 8.5mm long M3 spacers (8mm spacer and a 0.5mm thick washer).
