I have printed mechanicals parts to build a first prototype.

I have just received a display panel (TL070FVXS02)

I'm  working on creation a eDP cable between  motherboard and display panel

Display Interface Motherboard side

IPEX 20879-040E connector used to interface to an eDP display.  Note that there are signals
defined for both USB 2.0 and I2C touchscreens.  There is a PWM interface to control backlight
brightness, but the display currently used on the Framework Laptop converts that to a DC LED
control.  Note that pin 1 is on the left when looking at the receptacle on the Mainboard.
