Schematic for GrowBot PCB

Is there a schematic available for the growbot PCB? I didn't notice
any at Parallax when I looked.
I have the REV-C board on my son's growbot.

I wanted to hook up a Linefollower app mod and a Compass App mod on
the unit, and add the IR Object detection circuit as well (the one
from the Robotics manual that uses pulseout...38500 with two
transmitters and detectors). But I was wanting to see what I/O lines
are available for this.

What I wanted to do was setup the growbot for the DRPG RoboRama
coming up where it can run all the regular robot contests, by simply
changing the program from say, line follower, to quick trip, to wall
following T course, et cetera.
If I was real fancy I might try a BS2-SX and maybe setup the
pushbutton to switch memory banks to do the same thing.
Regards,
Earl

    I/O pin's 1,2,3,4,5 and 6 are available.

    Thanks I guess I didn't have enough coffee this morning, but I found it on
    my printer, I didn't notice that I
    had run out of paper until later.

    Anyway, If I plug in a Linefollower, Compass, and LED-Pushbutton Appmod
    units.
    And I either cover the photocells up or remove them along with the wire
    bumper.
    Then hook up the IR object detectors to the pins below.

    The question is whether the Linefollower would interfere with the Pin5 and
    Pin6 serial lines too much.
    and also with the IR object Detector LED transmitters. I would like to
    simply leave them all plugged in
    and have the program carefully use what is needed for that part of the
    contest. I simply ignore the things I am
    not using.
    The main process would be to use the line follower and Compass for the Quick
    Trip contest, maybe object detector too. Then use the Line follower and IR
    detectors for the wall following T test. The Linefollower would be used of
    course for the line following test.
    The LED-Pushbutton Appmod would be used to have the Growbot switch programs
    for each contest using a BS2-E chip with it's different memory banks.

    The Linefollower has LED's with 220 ohm resistors in series. It seems that
    the Stamp could run these along with the other devices OK. But would the
    Compass and LED-Pushbutton appmod serial driver have problems sending a
    signal back to the Stamp?

    Thanks for reading
    Earl


    GrowBot Pinout useage and information.
    P0 Right IR Object Detector (was PR2 Right PhotoResistor) input to Stamp
    P1 Right wall LED object transmitter output from Stamp
    P2 LineFollower (outer right LED)
    P3 LineFollower (Inner right LED)
    P4 LineFollower (center LED) also Left Wall LED IR Object Detector
    Transmitter output from Stamp
    P5 LineFollower (innerleft LED) also Compass Appmod Serial I/O line to/from
    Stamp
    P6 LineFollower (outer left LED) also LED-Pushbutton Appmod serial I/O line
    to/from stamp
    P7 Left Wall IR Object Detector Input to Stamp (was PR2 Left Photoresistor)
    P8 Speaker
    P9 BumperPost and LineFollower (output from LineFollower)
    P10 BumperPost
    P11 LED1 Left
    P12 Left Servo Wheel
    P13 Right Servo Wheel
    P14 Pushbutton
    P15 LED2 Right
    The IR Object Detector uses 4 lines two output to LED's and two inputs from
    detectors
    Remove bumper to setup robot for all of this stuff.
    P1 Right IR Detector Input to Stamp
    P2 Right IR LED output
    P10 Left IR Detector Input to Stamp
    P6 Left IR LED output
