PCB Size is 100x40mm

- The Connection from J1 to J2 is wrong - its 1:1 but it has to be crossed.

• Soldering Iron - with a Dip that can Handle Thruhole-Parts and 1206 SMDs, solder Paste…
  
• The other Parts from the BOM
  
• a Midibox Core32

All necessery Information is printet on the PCB, but also check the Shematic

then decide how often you want to order all off, the BOM Quantity is for 1Module
On one PCB you have 2 ident MidiIO-Modules, on JLCPCB you order typicaly 5 PCB, so your quantity may be 10x
BUT dont buy multiple Flatbandcables… these are hundrets of meter!

1 times: 45€ 25€ parts and 20€ shipping…shipping excl fat
if you go over 50€ shipping is free.
lets take a look if we order it
5 times: 95€ incl free shipping excl fat
10times:176€ incl free shipping excl fat

4x (or 20x) Leiterplatten Montageblock aka Standoffs 100x summed 30€
You will also need M3 Screws - 2 off them…
Also here it is clever to order 100 pieces for a cheaper price - you will need this on all my projects…

GERBER-Files Rev B for Production
I already received and testet Rev A, i hade some small Bugs which i got fixed with some wires…
So i got it fully working… the Bugfixes are includet in Rev.B
—never the less i did not testet Rev.B… since i have enough Rev.A for my whole Modular-Rack @ home
so feel free to test - and report!

- dont use this - because of J1-J2 connection is wrong (this matter if you chain 2 Midi-IO-Modules

I made a DXFFile which you can print, and drill it DIY or
you can send to:
frontpanels.de in germany 17,08€ a panel (5x-10%, 10x-20%, 20x-30%, 30x-40%, 100x-50%)
I tested one with them - and yes they looking good - and they fit!:

another good guy: The Beast - UK

Recommend Material
2mm x 128.5 x 17.78 Aluminium, anodised

A cheaper way is: order a 1,6mm thick Aluminium PCB as Frontpanel:
this are the gerbers:
gerber-euro_midiio_fp.zip
I have testet it, and this 1.6mm Aluminium from JLCPCB is too thin, i endet up by sandwith 2 off them togehter - so its strong enough, since the Labels are reversed when use the PCB reversed - i now removed them in this gerber file!

Use a other Midi-OUT-Activity Shematic! - its not working for high speed midi! - while Note-ON off is ok, Midiclock can make trouble (the Charge-Discharge Circuit in this Design is not sufficent for this!)
