It would be fun to be able to do a completely custom keyboard project… and actually, they mention that as part of the idea behind that breakout board. But ouch… 102 key keyboard = ($0.86102) + ($1.66102) = $257.04, and that is before factoring wiring, chassis, etc.
But for one-off applications? Still glad they’ve added this to the product line… the footprint of the Cherry switches are a little awkward if you just want to play with or proto them.

Wow – Glad I came back here! This pretty much sells it for me. Thank you for taking the time to test & post!!
A great idea - but unfortunately, the Atrix Lapdock can’t support actual 720p resolution (I know, because I’ve tried with multiple devices that can only output 720p). If you connect it to a PC and check, it only presents the EDID profile for 1366x768… So unless the pcDuino is actually configured (kernel compiled) to support that resolution, the laptop would be a no-go. That is really why this is an important question, because it is not mentioned at all in the manual.
I agree – this would be another major advantage vs. the RPi…
…and also level-shift some signals, it sounds like, based on SFUptownMaker’s responses to my inquiry above. Based on those answers, doesn’t stating “Compatible with Arduino Shields!” sound like a bit of an outside stretch? Something like saying a small-block Chevy engine is “Compatible” with a Suzuki Samurai, as long as you deal with the issues of “mechanics” and the other “electrical issues”… (Though I have seen people do that, too!)
So it sounds like what you are saying is that it isn’t really “compatible,” but more appropriately, “able to be made compatible” if you mechanically route the right signals to the right pins, and also level-shift some of the signals. Does that accurately sum it up?
Just trying to get things 100% clear, because this product is very genuinely interesting! =)
Amen to this – but it begs a different question. If you’ve got the Lapdock, you’ll probably know that it is somewhat limited in the resolution (presents 1366x768 as its only resolution); if the source device doesn’t support it, no luck. The RPi specifically supports something like 17 HDMI resolutions – including 1366x768 – but this one specifically only mentions HDMI 720p or 1080p 60Hz. If that is true, it probably won’t work with the Lapdock.
So can someone at Sparkfun confirm which actual resolutions are supported, if any, beyond the mentioned 720p/1080p?
Aside from that, this is a killer idea – and would be the deal maker/breaker in my decision to get one of these.
Ok – some confusion here: Above, in the product description and bullet points, it mentions that it is Arduino shield compatible… if that is so, what is the nature of this “Conversion Shield” which you are mentioning?
Hope you can clarify!

Ok… Not sure if you’ll be able to answer this one, but any idea what sort of noise this thing puts out at various voltage levels?

Hmm…. both worked fine for me from the start..
