For anyone struggling with the non-searchable vector font used in the PDF schematic, I reprinted the EAGLE schematic using searchable fonts for much easier navigation: boron-v1.00-schematic-searchable.pdf
Hi, I've noticed that the nRF52840 footprint doesn't follow the Nordic's recomendation regarding the thermal pad under the chip (shorter than the recomended). The vias under the micro can collide with the GND from the thermal pad (even with tented vias).
Are you aware of that? How did you managed to ensure the correct operability?
Thank you!
I am troubleshooting the Boron design for our application and only the V1.00 designs are available in GitHub, but I have version 1.10 on my desk. Can the latest design files be uploaded to GitHub?

There is no matching network between the ANT pin and the antenna connector, just a direct connection. I cannot find anything in the datasheet either about a matching network other than to use 50 ohm impedance.
Have you compared just having a 50 ohm trace directly from the pin to the connector vs. including the capacitor (15pf) and inductor (39nH) ?
Is it tested that the values used work well?
The argon and xenon repositories have the schematics in PDF form. Would it be feasible to add them for boron as well?
