Include 2.5mm pitch JST connector 3D model which was removed from the KiCad 3D library, export the .WRL 3D file of the board and the FreeCAD file generated from importing the model The 3D model files are contained within a .7z archive in order to minimize space required to clone the repo.

Przemysław.Brojewski <pbrojewski@onet.pl> Checked datasheet urls in all *.sch files, found 13 dead and replaced them with a working ones. Four components are marked as obsolete either by manufacturer or distributor: MFG part number comment --------------- ------- LMK107BJ475KA-T Non-preferred component for new designs. DB2J20900L Lifecycle (according to Mouser): obsolete. Datasheet no longer available on Panasonic website. FH26-39S-0.3SHW Component discontinued. Datasheet not available on Hirose website. SF56S006V4BR2000 Component pending obsolescence. Datasheet not availale on Jae website.

Updated the note on camera's PWDN pin (13) to correctly say that it has an internal pull-up and not a pull-down. Removed the redundant via that was on top of an already existing identical one on the UIM-DATA net (located at X=83.736372, Y=104.553716).

The highest VIH(min) it will get to is ~3.0V, which is completely fine.

ive permittivity of 4.1~4.11 The H parameter in the calculations was +0.21mm greater than the H used in the p rototype calculations (1.1mm thick board instead of 0.89mm thick) A DK value of 4.11 was used for the GNSS and WWAN antennae feedlines and a DK of 4.1 was used for the Wi-Fi/BT feedlines since the operating frequency of the GNSS and WWAN is generally a bit lower than Wi-Fi/BT. The NANYA NP-180TL spec sheet is also included. The specific prepreg/core/substrate/dielectric used is NANYA NP-180**TL** which has a DK specified as 4.1-4.3 @ 1GHz.

Add a TXB0101 logic level translator to the LCD_RESET# signal, the VIH(max) if the LCD's reset pin is 1.8V so the voltage needs to be translated from 3.3V logic down to 1.8V logic The active TXB0101 level translator is used so that the pin can continue to be externally pulled low by a 10k resistor. The behavior of having this pin supplied with a logic level exceed its maximum rating is unpredictable (could be fine but could also act in unexpected ways). The TXB0101 is already used in the design as U1302, so now there will be 2x of these per board. This also requires two additional 0402 X5R 10V 100nF caps (already have 87 per board of CL05A104MP5NNNC / EmCraft PN: E-CAP-003-01, will now be 89 per board).

Specify in the schematic note that the OV5640 camera's 7-bit slave address is actually 0x3C (not 0x78 which is it's 8-bit write address with the LSB r/w bit set as 0) The OV5640's datasheet mistakenly says 0x78 for the SCCB slave address (it's supposed to say 0x3C). In binary representation it's 0111 110x, with x as the r/w bit.

Use the new MDT320E03001 M.2 socket footprint in the layout, make the corresponding changes in the layout for this new footprint to work This M.2 socket is used instead of the previous one due to the M.2 module having components on the back which are as tall as 1.35mm.
