<br>
I recently purchased an Intellijel 7U Performance Case, and it’s nearly perfect.<br>
<br>
Who makes the M3-threaded PCB mounting brackets that are soldered (in three places) on the MIDI JACKS rev003 board? I think I need to buy some of these. Are they a custom part? … or are they available some place like Mouser, Jameco, or Digi-Key?<br>

I’m in the process of designing a replacement for the MIDI board that would have active MIDI circuits. It’s intended to interface with a Euro module of my design that provides 5 V and serial data on a single header, without the optoisolator or current loop conversion. I could build an adaptor with the needed circuit somewhere else in the case, but it seems like the best option is to design a replacement PCB that will fit exactly where the MIDI JACKS rev003 does now. So, I’ve measured the placements for the MIDI jacks, USB jack, and screw holes. I already have the USB and MIDI jacks, so all I need are those metal brackets that solder via four pins each to the PCB and have M3 threaded holes in the right position to align with the 7U case.<br>
<br>
My design has jumpers to switch MIDI THRU between a buffered version of MIDI IN or a second MIDI OUT. In my case, the extra bandwidth of a second MIDI OUT will probably end up being necessary.<br>
<br>
I plan to keep the USB wired to the 10-pin header in the same way for compatibility with any existing (1U?) modules that might use USB, but will leave the MIDI pins unconnected since I’m taking them over.<br>

p.s. I’ve already designed and built a 1U module that is a buffered 4-channel 1/8” to balanced circuit that connects to the existing Audio Jacks Board v2 via the 10-pin header. I really appreciate that both the Tip and Ring for all four jacks are brought to that one header. I ended up making all four jacks into outputs, and that was simple because the Audio Jacks Board is passive - so the direction isn’t baked in to the hardware. Of course, the labels painted on the case are no longer totally correct, but this is a personal modification for a 4-voice modular synth with individual balanced voice outputs.<br>
