    Why are all the best drivers common anode (TLC5940) and all the best LEDs (this one, COM-10595, COM-10390) common-cathode? :( :( Where’s the sweet spot? What’s the best way to drive those common-cathode LEDs with PWM?

    fwiw the lead width on these (according to datasheet and visual) is 0.8, and the pitch (on each row) is 2.6. I can’t find a jumper for a lead width of 0.8 anywhere… I guess I am just going to go back to soldering the leads directly on to the part :(

    Those ‘pins’ are much wider than standard IC pins, so be aware of that. I’m not sure if there is a standard for that particular type of pin? If I could get female jumper leads for those pins, I would do it in a second, but I don’t know if they even exist… Do you have any leads on that? (pun intended)

    Can anyone suggest to me a good way to get these hooked up without custom PCB layout? I can’t find any connectors or protos with the proper spacing for the pins on this part. I could get the drill out, but geez. This part is proving very hard to work with… (I second the call for a breakout board for this guy)

    I have this board powered as per the bildr tutorial. That part seems to work just fine, but… I wrote a simple on/off sample which worked for about 30 seconds or a minute, and then suddenly one of the channels goes into perma-ON mode (dims a bit based on load on other channels, but otherwise ON). I have disconnected everything and reconnected, re-uploaded code etc. Still has same issue (Channel G). Is this board just really low quality, or is it issues with the triacs as some have suggested? Any tips on how to troubleshoot this?
