Will an official KiCAD library and footprint be released for the Omega2S?
-
For designing products which use the Omega2S, an official KiCAD library and footprint would be very useful. Are there any plans to release any?
-
@Zebulon-McCorkle I would like to get an official footprint from Onion as well!
However, for the time being, you might want use my KiCAD library. It has a Omega2S footprint which I could already test to some degree (manual soldering on one prototype board - I had access to an early Omega2S sample).
So that footprint should be fine, but of course, it's not official and there can always be details… Just create a PR on github if you have improvements…
-
@luz Oh, that's great! I'll get working on my design and be sure to PR any improvements I might make.

Onion just released a
.dxf
drawing for the Omega2S footprint, and a.pcb
file presumably containing a footprint (but not in KiCAD format), see here.Comparing the
.dxf
with my Omega2S footprint (which I designed for manual soldering), the pads are smaller and reach a bit more under the Omega2S. This requires extremely precise placement because of the very close proximity of the non-masked shield housing contacts to pinsC24
/B24
. If the part is only a fraction of a mm shifted right or left,C24
orB24
gets shorted to GND (shortingC24/XTAL_FREQ_SEL
is particularily interesting, because then the Omega starts up, but with a wrong frequency, so console has a weird baud rate, and everything else depending on timing does not work. That's how I learnt to pay attention to these pads...)So I think the official footprint is probably ok for automatic placement, but mine is safer for hand-soldered prototypes.

Here you are, unofficial (my own project) but usable Kicad library, footprint and 3D shape:
