How many Plasma lights can the Picade X HAT drive?

I’m considering a build that could potentially use more than 10 buttons, and the Plasma buttons are definitely pretty! Can the Picade X HAT drive more than 10 Plasma buttons, or is 10 it’s limit?


They are chainable and you can alter the number of ‘pixels’ in code. The limiting factor would be current, I’m not certain how many would be supported before brownout.

Yeah it would be 3A minus what the Pi and picade use. Maybe 1A to play with? Probably slightly less than that. My best guess anyway.

I’ve run 16 in series, but no more than that yet. You can mitigate the power problems you might get from trying to run more by just running them at a lower brightness.

Thanks gadgetoid! I’ll keep that in mind for my build.
