I’ve got my Plasma 2040 working nicely with an LED strip, but I’d like to use a passive IR sensor to trigger it. Do you have a pinout diagram for the Plasma, so I can use one of the labelled pinouts as a bog standard GPIO input to sense when the IR is triggered? You’ve got labels on them, but I don’t know which GPIO each one is linked to.
Thankks
There’s a downloadable PDF schematic for the Plasma 2040 on the Pimoroni page for the product at Plasma 2040 – Pimoroni
That should show what’s broken out where.

Thanks, David. Yes, I found the schematic before posting the question, but it makes no sense to a bear of little brain like myself.

Looks to me from this
That the SDA/SCL broken out on the edge of the Plasma 2040 are GPIO20/21 respectively - so I’d imagine you can use them if you’re not planning on using I2C
@kevpartner did you get this working ok? I’ve just received my plasma2040 and am looking to include a reed switch as a door sensor.

Can confirm: works. Used pin SDA/GPIO20 (and then ground) to connect the reed switch. Working nicely.
Under-stairs cupboard now looks a lot funkier :)

Wow looks great, I’m trying to get this to work too. Do you have any code to share please?
Did you get this working? I can probably help you out
For anyone landing on this post years later, like I have; the pin that is assigned to the screw terminal labeled “DA” is GPIO15.
I don’t feel like the available schematic makes that very clear, I spent too much time trying to figure this out to not post it in the thread that kept coming up in my search
Ouch! This is actually available to python. You just have to print “plasma2040.DAT”. Quick trick in case you need to do this again…
