If you missed the prop stick for $50, maybe you can use the spin stamp for $24.99.

Keep in mind it doesn't have all the pins exposed and no USB connection, but it might be perfect for use in a finished product that doesn't need as many.

    yeah, that was yesterday's price. that's why I posted it here. I figured we could all use an Xtra 1 or 2.

    Good deal! I love the SpinStamp and·it's great to pick up another one·at half-price.·I've used·mine in a couple of small robotics projects. Thanks Parallax!

    The pdf for the spin stamp still says pins 1 thru 3 are Don't Connect and no further information is available. I suspect that's not true. Any comment, directions to their explanation?

    Google on: site:forums.parallax.com "spin stamp" "connection details"

    They are serial pins, plus pin 3 is ATN. They might future plans for them (I remember that from another post somewhere).

    Hey, what's with the "Do not connect" and "Connection details not available at this time" on the RS-232 serial I/O pins on the Spin Stamp? From the schematic it looks like it will handle RS-232 levels (using the included transistors). But the deocumentation says not to use them! What gives? I'd really like to use these with the existing Basic Stamp serial I/O connector on my motor controller, to communicate with the laptop (not for programming). That way once the chip is programmed, I can keep my prop clip for other things, and control the circuit through a PC serial port.

    "Because the transistor is switching 3.3V and not 5V as with the stamp, some computer serial ports don't recognize that as a valid high voltage. Rather than have people call tech support complaining it doesn't work for thier system, we don't guarantee it's functionality on all systems. If you are working in an RS232 system which supports lower voltage levels by all means use it, it should work just fine. If it doesn't and it's critically important you can use a MAX3232 or some other level shifting external circuitry.
