thats pretty sweet. right looking dotpitch too.

the stm32 is not a 5v part. you'd have to use some output buffering chips to get 5v. depending on which stm32 chip, its gpio pins can push about 25ma. i would try sending the signals through one of the many buffer/line driver chips like 74hc244 74hc366 etc.

very strange that such modern panels need 5v signal lines?

sweet. ordered last night.

gonna see if I can wire up a little pic32 + rs485 and get it hooked up to my System Shock board set!

sweeet. panel showed up nicely. gonna have to see about making my own controller now! thankfully grandma is taking the kids on the weekend! YAY

hmm i posted on his facebook on the page that had the actual pin2dmd screenshot on the panel, comment is gone in < 5 minutes heh and the photo is gone too. heh. he certainly knows he should not be using pin2dmd for commercial purposes per the CC-NC license... you should report it for using your intellectual property on the facebook page. i think its an option on that pages 'report' button.
