UPDATE: hooray, nILS (ONCE AGAIN ;)) updated the layout! Thanks nILS. ---------------------------------------------------------------------------------- * no more piggy-backing, the board is now fully stuffed with everything that's on the small gm5 board (which you don't need for this apparently) * added 74HC14 inverters to add LED support for each MIDI In and Out * board size is roughly 23cm*5cm (8.8"x2.0" for the metric impaired) ---------------------------------------------------------------------------------- Hi everyone. Here we try to gather interest in GM5 5x5 (5ins-5outs) expansion pcbs, in order to make it full scale product. http://www.midibox.org/dokuwiki/gm5_expansion_5x5_board For those who don't know what i'm talking about, GM5 is a usb-to-midi solution. The board manufacturer, Ploytec GmbH, made PCB layout with 1 midi_in and 1 midi_out only, while supporting up to 5in-5outs by utilizing dedicated headers. We try to simplify your soldering experience and avoid prototyping the remaining 4in-4out board. Nils already created the dedicated pcb for diy etching. Now we're headed for (to be) manufactured model. The aim is to manufacture this or similar with professional pcb manufacturer, all fancy silkscreening, laquer, etc etc. The reason for not being posted in group buy section: it all depends on your interest; and before we shoot, we want to smell the ground. Post your considerations, ideas, and put your credentials on the wiki if you'd like to have some of these too.
