Added a drawing to illustrate the issue of ear overlap.

instead of cutout there could be just drilled holes.  There are extra long headers .

This is the shape i propose to make the PCB

Good stuff, I'll take a look this week and make the changes.

If you have KiCAD  version  of your board I can do the modifications.

[TERRA Operative]

Only Diptrace unfortunately.
I have yet to figure out how to use KiCad for more than 30 minutes without rage quitting... Open-source syndrome with the UI and all....

Looks like diptrace available as freeware up to 500 pins.  Could you  send the schematic and design  files?  I will see if there are export options or just use diptrace to modify .

Here you go.

This is what i was thinking

[kawal]

I don't know whats up with Diptrace, but not happy. Again the footprint is wrong for U3. The footprint is too big for SC-70 and too small for Sot-23.  The Sto23-5 used is not standard size of 0.95mm pitch but 0.65mm pitch.  Not sure what that even is.  .......


OK  figured it out SOT-23-5 0.65mm pitch is SC-70-5  OMG!!!

Ok, I've made another revision with the clearances made for adjacent screens.
I also measured up one of my 3478A multimeters and adjusted the board outline and mounting hole positions to be more accurate.
And finally, I tweaked a few things and have updated the BOM file etc to use more of JLCPCB's basic parts to try to reduce cost and make assembly easier.


I'm getting a quote on a run of 20, 10 of which will be spare, so in a while I might have a bunch for anyone who wants some. But no promises how long away...
