An interesting part
« on: July 04, 2024, 12:27:05 am »
This probably happens all of the time, but I thought this was funny.

Recently I was looking at small OLED displays and came across the 'World's Smallest 0.32" OLED 60x32 Display Screen'
https://www.tindie.com/products/questwise-ventures/worlds-smallest-032-oled-60x32-display-screen/

Call me a nitpicker, but I'm pretty sure that all 0.32" displays are the same size.

OK, That's probably why I never get invited to the fun parties.

But there's more!  Better hurry, because there are only six left at $16.50 each.   Of course I want to see the datasheet:
https://d3s5r33r268y59.cloudfront.net/datasheets/33662/2024-02-10-02-08-26/TOX032FSWAG02_0.32-Inch-OLED-60x32-White-I2C-SSD1315.pdf 

Maybe I'll use one in a project some day.  I wonder if JLCPCB has one (otherwise I have to buy a reel of them). 
Well, no.  That part number isn't known.  But they do have an "Organic Light Emitting Diode Display Screen".  A poor substitute?
Especially at $1.24 each.  In all fairness they have no stock, but LCSC has 143 of them for a slightly lower price ($1.28).  Now I'm sure that we are talking apples and oranges.  But let's see...

Spoiler:  Pretty much the same datasheets (word for word) with two different manufacturers.

Interesting, here is the LCSC link: https://www.lcsc.com/product-detail/Organic-Light-Emitting-Diode-Display-Screen_span-style-background-color-ff0-Newvisio-span-X032-6032TSWAG02-H14_C18723006.html
That manufacturer has quite a few options.

I wouldn't think too much about the cost on tindie, its just some person listing it for whatever they feel like.

Looks like the Tindie seller has designed a base PCB (providing the passives for the charge pump and exposing castellated pads for the I2C). I think most people would be happy to have those parts themselves on their custom board - but I guess that partially explains the markup!
