thinking about propeller questions
I'd like to start using the propeller and have the following questions:
1) Can the propstick USB device be powered from the USB hub through the voltage regulator without additional power requirements?
2) Can the propstick USB emulate a serial port and send data to the comm port easily?
3) The propeller demo board seems to have everything the prostick usb has and more - is there a reason not to go with the demo board to evaluate the propeller over the prostick?
4) The basic stamp used to have a carrier board that you could plug the chip into and it would give you screw terminals that connect to all the output lines. This makes connecting wires much easier than dealing with them falling out of the breadboard. Is something like this available for the propeller or aftermarket?
I've been using the Silabs Toolstick and TI EZ430 chips but think I'm going to move to propeller for the savings with board design and stop using the interrupts.
Thanks for answering my questions!

Comments
1) No it needs a seperate supply. Terry Hitt (Bean) has a USB powered Propeller board, but Parallax doesn't offer any USB powered dev boards.
2) Yes it can
3) The advantage of the PropStick USB is that you have access to all of the Propeller's I/O. The demo board only has 8 unused I/O pins for you applications.
4) The Propeller ProtoBoard would be closest of the Propeller products to the Carrier Board.

I use a protoboard and take the supply from the usb-clip. So I can work with my propeller, whenever my notebook is running! The photos show how the wire is fixed and connected to the LED's.
Both my TI EZ430 and SiLabs Toolstick draw power and include a USB connector.· I know Hitt Consulting makes a board that has integrated USB power and hope other people could point me to others...
Thanks!

You'll always have as many take-offs as landings, the trick is to be sure you can take-off again
