We have the pinout for the mainboard-side of both FWL13 & FWL16.
And we have the FWL13 display-side pinout. But I don’t recall seeing the FWL16 display-side pinout.
It’s a BOE NE160QDM-NZ6 display for the FWL16. I don’t think the datasheet, which would have the pinout, is available publicly. panelook.com/NE160QDM-NZ6_BOE_16.0_LCM_overview_65105.html
I vaguely recall someone on the forum mentioning some datasheet that they had but couldn’t share (due to being marked to warn against sharing iirc). Not certain it was the FWL16 display datasheet but I do think it was.
