copy following Lines in the box - and make a new project
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
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:
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!
Since i already debugged Rev.A - and this is the overworked Rev.B - there should not be much to do, except to test the gerber filers… i am happy with Rev.A (have still PCBs so no check of RevB in near future!)
