The SpinStudio Input/Output/Servo adapter allows the user to directly access IO pins. It also includes 8 3-pin header connectors for easily connecting standard servos, Serial LCD's and/or Parallax's Ping ultrasonic distance sensor. You could even use a combination of all 3! There are current limiting resistor's inline between the Propeller and the servo headers, but the female I/O connector provides a direct line to the Propellers pins with no resistor.
Assembly
Plan ahead! Figure out ahead of time
what componets you want to install on the board and where you want
them. Included are 8- 1k ohm resistors. This resistance is
appropriate for either a servo, or Ping. The board could also be set up
with a smaller value of resistance and solder in LED's instead of the
servo headers.
Start by inserting the resistors of your choice in the 8 positions in the area labeled with a red "A" in the diagram above. Turn the circuit board over and solder these 4 resistors in place. Trim the protruding resistor leads. It is not necessary to install all the resistors at this point if you are undecided, you can always add them later.
Put the External Servo Power connector (marked with a green "B" in the illustration above) with the wire openings facing the right when the module is held as shown above. Solder the 2 pins from the reverse side.
Now install the 20 pin SpinStudio connector, blue "B". Note - This component is inserted from the bottom of the board, and soldered on the top, opposite of the other components! You may want to solder 1 pin first, check to be sure the connector is positioned snuggly against the bottom of the circuit board before soldering the remaining 19 pins. Also you may want to turn the circuit board while soldering, to "attack" the pins in each row from a different angle. How you solder is up to you, but just be careful not to create any solder bridges, or dry solder joints, as they may be difficult to track down later.
Next install the Headers in the positions labeled "C" above. Put the 3-8 pin male headers in their holes. It may be necessary to gently but firmly press the module face down on a flat surface to "level" the pins. It may also be a good idea to plug the female header used in position "E" into these male header horizontally to help properly space them until they are soldered permanately in place. Now Apply solder, following the same precautions as you did for the 20 pin connector in the last step.
Now you can insert the 3 pin male header in the position marked with a green "C" above, and the 8 pin female header in the position marked with a green "E". Again carefully turn the PCB over and carefully solder in place.
All finished!
