Dennis Field / dvk-mx8m-bsb - History

Update the fabrication drawing file with more information

This file was created by exporting both the Cmts.User layer, as well as the NPTH&PTH drills into separate DXF files, then combining them in the footprint editor, finally, this new footprint made from both of these is imported into the layout and re-exported as a single DXF.

Update the BoM with all part numbers from the "purchasing" BoM in NextCloud, update all manufacturing-related files after the last few commits' changes (including new assembly & fabrication files as requested)

Move some of the traces away from under the inductors (traces on layers In2.Cu and B.Cu)

Make a few improvements to the 5V buck converter's layout after the pin number mistake was fixed

Proposal for treatment of high accurracy resistor in BoM.

Fixed an erroneous pin swapping in U402 (MIC2876).
Corrected library entry.
New placement and wiring for resistors near U402 in layout.

The signal CLK02 (clock supply for ethernet PHY) was surrounded with GND traces to form a shield against the static field (25 Mhz present).
The same was done now with sigbal CLK01 (clock supply for camera)
.

Bring back the current version number (v0.1.0) on the back silkscreen by replacing the word "Preliminary" with it

Make the backlight boost converter compensation capacitor (C459) 10nF instead of 100nF (was a typo), make the charge controller's PMID capacitor (C302) 10uF instead of 8.2uF since it is a more common value and is what is being used on the charge controller's eval board, select a 10uF 0603 X5R capacitor rated for 25V for both the PMID cap and the 10uF cap on VBUS, update the .ods BoM with tolerances & ratings for the caps and resistors which will be supplied by the PCBA house, export the component-placement-list file (dvk-mx8m-bsb-all.pos) which gives the coordinates of all components with respect to the top-left fiducial mark, re-export the gerbers for preliminary review (add silkscreen which states that this is preliminary instead of a version number), make a few minor improvements to the board's routing in various spots, update the IMU footprint so that its silkscreen which gives the axis directions is visible on the board, some footprints were updated to be defined as SMD footprints in order to show up on the component-placement list (strictly through-hole components are not listed)

The 0603 10uF 25V caps have been ordered and will be shipped to wherever the assembly is done. This commit contains the preliminary materials which will be reviewed (BoM, .pos file, and gerbers all zipped).
