nRF5 eagle reference designs on Github are incorrect

Eagle pcb and schematic reference designs on github are incorrect.

Reference nRF52840 pcb schematics and layouts are exactly the same for examples 2-6. I believe each is a copy of var4. The schematics for these reference designs are listed correctly in the specification document but do not match what is included here.

shas for the files mentioned:

  • Hi Sam

    Thank you for notifying us! You're correct that they are copies of variation 4. I've reported this internally, and someone will update these files soon I hope. In the meantime, please use our official hardware files for reference. Altium schematics and PCB layouts, as well as the correct .pdf files,  can be downloaded here. I also noticed that the capacitor value of C14 in these eagle files are wrong, as it should be 1uF instead of 4.7uF. Please keep that in mind if you're going to develop a PCB layout before we are able to update them. 

    Best regards and thanks again!
