mintyPi Screen

Post by wermy » Mon Apr 24, 2017 12:17 pm

Lost of questions and discussion around this (and availability), figured I'd start this to avoid gigantic threads where info gets lost. :)

Here is the screen I used:
http://www.ebay.com/itm/252135075697

The one you want is 320x240 pixels, and looks like this on the back:

Note the number of pins (9) and the order of them. The add-on board Helder and I are working on (which will let you use a nice, thin ribbon cable in stead of hand-soldering 9 wires to connect the screen to your pi) will use 9 pins, in that order.

Some other variants have a chip on the back that is too tall for the mintyPi (ignore the SD card slot, you remove that when you put it all together):

From what I've seen though, these ones usually have the wrong pin configuration and are a different (lower) resolution.

It seems to be in limited supply at the moment. It can be found on some sites like alibaba still but with minimum orders of 10 or so units, but check ebay and amazon - search for "2.2 SPI screen".

ILI9341 screens should be fine software-wise (may need a slightly different configuration), but I'm not sure if the components on the back are any taller (there's not a lot of clearance behind the screen as you can imagine).

Adafruit's 2.2" screen looks like it might work: https://www.adafruit.com/product/1480
It's almost identical size-wise. But it's expensive and the pins are in a different order (meaning you couldn't use the screen add-on board Helder and I are working on).

ElfUp messaged the ebay seller and got this response:
We can not ship out this item from warehouse now. We found that the whole brunch of items get problems when we checked them again before ship them out. As a responsible seller, we never ship out the defective items to our customer. We have ask for the large cargo but it may need another 2 weeks to arrive.
There is one seller on amazon that says they expect to have it in stock in the next few days:
https://www.amazon.com/4-Wire-Display-M ... B01N3L01BB

So it sounds like it may come back in stock once that is sorted out. If you find any promising-looking alternatives, or find it in stock elsewhere, post it here!

I was able to get the screen Wermy posted from ebay.ca luckily, but as seen it is now sold out.

I also bought this one from aliexpress before he posted the link though...The one from aliexpress doesn't specify if the Driver IC is ILI9340 based though, and the seller was not helpful when I asked. It was cheap enough to buy one anyways. It shows 900+ available. But....It also shows 2.2" in the title, and 2.4" in the description, so i'm not sure what it actually is. The seller was also not helpful when I asked about that as well.

Hmm, I'm wondering how tall that chip on the back is:

Edit: Also looks like the pins are incompatible with the screen add-on board we're making. Which should be fine as it's optional, but something to consider.

That link didn't work for me - however I found it by searching the title (looks like the right one - I hope!):

Ordered one then noticed the date changed to April 29th.

Added some more info in the first post to make it easier to tell if you have the right screen.

Is there a difference between the ILI9340 and ILI9340C in terms of compatability?

If not, there's a US-based eBay seller that has 9 screens in stock, with free shipping to the US*. If anyone's in a hurry. https://goo.gl/wij6Er


*and stupidly expensive shipping to Canada. :evil:
