Small display eyegasm


#1

240 x 240px 1.54in SPI display driven by an STM32F411 and NETMF 4.4

Image doesn’t do it justice, in the flesh it looks almost as good as my mobile screen :grin:

Hand soldering the 0.4mm pitch connector was entertaining :joy:


#2

and you know how I feel about displays…


#3

funny, the picture did not have the same effect on me! :sleeping:


#4

Where did you get your display from?


#5

@Mike, you must be getting old :yum:


#6

Display’s came from the manufacturer

#7

@Justin - A new toy or something for a customer?


#8

I ordered them for a potential customer project but it will also turn into a toy :blush:


#9

Wiring has been cleaned up.

I still think Gadgeteer modules are the business :grin:

Cellphone camera doesnt do this little display any justice…


#10

time to klean that keyboard my friend ! :wink:


#11

Can you guess the provenance of said keyboard crumbs? :joy:


#12

Full ack. It’s a pity the connectors are so dead expensive. I switched to 10-pin headers, keeping the pinout, for designed PCBs. I still have a small stock of Gadgeteer cables and breakout headers so I can attach the modules to a Gadgeteer mainboard.

The display looks really cool indeed!


#13

Good idea re headers.
Yes the Samtec part specified is very expensive but there are alternatives that are cheaper. DF Robot do 10 at 0.29ea and in a 100’s around 19c from memory.


#14

You know how i feel about Gadgeteer!!


#15

I googled and found: https://www.dfrobot.com/product-1111.html

Oh, I didn’t know that they exist! It’s still not very cheap, but at least justifiable. I searched for cables also, do you know if any compatible cables exist as well?


#16

Cables are a bit harder to find in small quantities but if things go according to plan then i will offer them in singles at a reasonable price soon.
