As the MOTM-960 is not to my liking because the spacing between the slots is too crowded I made my own busboard design with 4 rows instead of the 3 of the MOTM-960. So it has footprints for 28 headers instead 21. 4 of them can be fitted alternatively with Curetronic/Eurorack connectors and 2 of them have the additional 4 pins to allow the fitting of 14 pin Club of the Knobs connectors. Because of the width I could only fit in two of the COTK connectors there.

As I got a question regarding diodes and capacitors: I think protection should be done in the module itself and the PSU. Coupling, too, that's why there are neither diodes nor capacitors on this busboard.

As images are better than 1000 words here is a picture of the populated prototype:

The size is 20 cm x 9 cm and the PCB is double sided with through plating.

If there is enough interest (let's say 20) I will order a batch of 50 PCBs which would then cost 18 € each plus postage and packing.

Edit: Ordered the batch.

Edit 16th February, 2017: 0 boards left.

Currently there is interest for 10 boards, so 10 to go for starting a batch.

Open for comments and improvement suggestions. I mainly didn't add a terminal block footprint because I only like the one on the MOTM-960 and don't know where to get it (and with it a datasheet with a layout description).

To give this a bump here is pic mounted inside a cabinet and an MOTM cable:

It shows that there is enough space for the cables to not have to bend them.

I already installed a page as it seems likely that I get enough interest for batch (currently there have to be additional interest in 7 PCBs to make it happen):

Please let me know if you want one. I guess that stock will last some time.

What do you estimate shipping would be to Chicago, IL, USA? For 3 if it's important.

Edit: Is anyone interested in complete kits with MOTM connectors and those metal connectors for the PSU connection?

Thinking about using 2-3 of them myself and instead selling my Synthtech MOTM-960 boards. Confused

All gone now

Edit: If someone tells me what I need to export Gerber files in the right way from Sprint Layout I can put those online.
