yeah, they all look good, but you don't necessarily "NEED" them to be PCB mounted, and the memory card reader will almost certainly be a waste of time on the Pi (though I think a few people have gotten them working?)
Im sorry im not sure what you mean not needing the PCB? Aren't those the driver board and needed to make the screens work? Yeah those sdcard adapter on there are probably useless.

look at this post to see what I mean:

with those SPI screens, there is no driver board, the ILI9341 IS the driver. SPI is the interface so all you need is the software driver for the SPI protocol. those PCB's are mostly just physical carriers. they put all the extra crap like SD card slot to make it worth their while making PCB's for them otherwise they'd look just like a big version of moosepr's tiny thing. look at the minty pi PCB sale thread. if you look closely at the display PCB you'll see it's not doing much except hosting a resistor

Thank you so much!

this one looks interesting from a mounting perspective... (could have it solder to the PCB below it (as you look at it) so it wouldn't need to take depth behind it)

looks nice, landscape screens are what im after atm! waiting on an ili9342. im not loving the lack of pinouts though :(

I was gonna ask you again about the pcb but since you already answered that here on your edited post, thanks again!

I actually have one of those as a dash mount ;)

all the 1.8" ones i find are 128x160
You're correct the 1.8 is that resolution I was mistaken on that size model but the other are the correct resolution.

Here is the "driver" (note it won't exactly look like this or mount this way, it's just a prototype):

@kite this is what I was talking about. Would you be selling something like this in the future?

The pcb sticking outside might have an advantage of soldering them like MintyPi pcbs are soldered to each other to reduce the combined height.
