  • When you can, an idea on when you expect to be caught up would be lovely, but I suspect all of us can understand it being "It'll ship when it ships" today :) Good to help you debug things, I've been there too, glad you have good co-workers :)

  • They've seen that there is a problem and say they plan to fix it, so I hope they'll take some back orders from me in a few hours - I was glad to see that as otherwise most things I wanted to get were already out.

  • Looks like you could even mount it on the edge of a PCB, with a little elbow grease; For prototypes that saves drilling some holes by hand.

  • Another thing to point out is that the larger the resistance for the pull-up, the slower the pin is to respond to voltage changes. This is because the system that feeds the input pin is essentially a capacitor coupled with the pull-up resistor, thus forming a RC filter. And RC filters take some time to charge and discharge. If you have a really fast changing signal (like USB), a large pull-up can limit the speed at which the pin can reliably change state.
    The -smaller- the resistance of the pull-up, the more effect it'll have on the input signal, though; a pull-up is there to help the input signal to fall into the reading circuit's logic levels, a 0.01 Ohm resistor would -really- mess up a USB input sighal, a 10Meg resistor would usually not do much for you.
