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
.dxfdrawing for the Omega2S footprint, and a
.pcbfile presumably containing a footprint (but not in KiCAD format), see here.
.dxfwith 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 pins
B24. If the part is only a fraction of a mm shifted right or left,
B24gets shorted to GND (shorting
C24/XTAL_FREQ_SELis 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:
