Connecting Pimoroni Pico Display Pack 2.8" with Adafruit Macropad via STEMMA QT

Hey everyone,

Did anyone try to connect Pimoroni Pico Display Pack 2.8" with Adafruit Macropad RP2040 via STEMMA QT before? I’m very newbie about these stuff and I’m trying to learn how to use Stemma port connections. I was planning to use pimoroni display for showing detail text stuff and small screen of macropad for basic category info when I click any key on macropad. If it’s not possible, do you have any suggestion for any screen to connect to macropad via stemma?

I was thinking to buy this display but it’s kinda expensive to try and fail so that’s why I wrote here :)

Thanks all for all helps!

Most displays are SPI, not I2C. Stemma/Qt is an I2C connector interface. So the Pico Display Pack is no option for you.

What you can use is a 128x64 monochrome OLED display. I would not go for the 128x32 variant, that is too small. On the 128x64 you can display about 5 lines of text with 21 chars each.

You can see an example here: https://github.com/bablokb/pcb-pico-datalogger/blob/main/examples/adalogger.jpg?raw=true

If you want a display with integrated Stemma/Qt, then you pay a premium price. Normally, these displays have a 4-pin connector. I usually attach them with a Stemma-DuPont adapter cable.
