Board of Education Shield (#35000)
Plug this shield into your own Arduino
®
module to give it the useful features and form factor of the
original Board of Education
®
. This shield makes circuit prototyping simple and convenient with a 2 row x
17 column breadboard. Headers along the side. top, and bottom provide easy access to supply voltages
and the Arduino module’s digital I/O and analog inputs. The Board of Education Shield’s four corner
mounting holes and servo ports make it compatible with the Boe-Bot robot chassis, continuous rotation
servos, and many sensors and accessories from Parallax.
The 3-position power switch allows you to turn on power in stages, first to the power header above the
breadboard, and then to any servos plugged into the ports. This is especially useful for cutting servo
power so that you can monitor sensors on your breadboard while keeping motors from moving. This
board also has a RESET button for restarting the program and pass-through headers for stacking more
shields on top.
Features
17 row x 2 column breadboard with adjacent headers for Vin, 5 V, 3.3 V, GND, digital I/O and
analog in
Onboard 5 V regulator supplies up to 1 A for robotics and animatronics applications
Onboard 3.3 V regulator supplies up to 250 mA for project circuits and accessories such as Digi’s
XBee
®
RF modules
4 servo ports with power selection jumper for regulated 5 V or Vin (Arduino’s supply voltage)
3-position power switch for power header or header + servo ports
RESET button resets the Arduino
Supply indicator LEDs for breadboard
and servo power

Assembly Instructions (Arduino module not included)
Step 1
The four groups of pins under the Board of Education Shield plug into the four Arduino socket headers.
If you have an Arduino Mega, the four pin groups fit into the four headers closest to the USB and power
connectors. If your Arduino is Revision 3 it will have UNO R3 or MEGA R3 on the back. When you have
socketed the shield, Revision 3 and newer revisions will have two empty pairs of sockets at the far left,
closest to the USB and power connectors. Earlier revisions such as 2, 1, and Duemilanove have the same
number of sockets as the shield has pins, so there should be no empty sockets on the Arduino’s left side.

Mega R3
Step 2
Carefully line up the shield’s pins with the Arduino’s sockets. Before pressing the two boards together,
look through the shield’s three smaller mounting holes from straight above. They should line up with the
mounting holes on the Arduino module.

Step 3
Make absolutely sure you have the pins correctly aligned before continuing!
If the pins are
aligned wrong, your Arduino module could be damaged when you connect power.
GOOD: pin alignment correct.
BAD: pin alignment wrong!
Uno R3
Correct: gap in pins lines
up with gap in sockets.
WRONG! STOP!
There’s a pin between the
gap in the sockets, so it’s
not correctly aligned.
Unplug it and try again.
Uno R2 and older
Correct: gap in pins lines
up with gap in sockets.
WRONG! STOP!
There’s a pin between the
gap in the sockets, so it’s
not correctly aligned.
Unplug it and try again.

Step 4
Press firmly to insert the Board of Education Shield into the Arduino board’s sockets.
Press the BOE Shield
onto the Arduino
Standoff Assembly Options (additional hardware sold separately)
Tabletop standoffs
are recommended to keep your board from tipping while you build circuits.
(4) Parallax #700-00028 – Machine screw, 4-40 x 1/ 4” pan-head Phillips
(4) Parallax #700-00060 – Standoff, threaded aluminum, round 4-40
#1 Phillips point screwdriver
Thread a screw through each corner hole on the Board of Education Shield hole from the top side.
Thread an aluminum standoff onto each screw and tighten gently.
Note: the corner mounting holes are plated and connected to the Board of Education Shield’s ground
plane, and so will the aluminum standoffs when attached in this manner.

Board-connection standoffs
attach the two boards together. They are recommended if you frequently
connect and disconnect the Arduino’s programming cable or external power. They are also useful for
applications that involve vibration or acceleration forces.

#1 Phillips point screwdriver
Check to see how many spacers will fit on your particular Arduino module. Most boards will
accommodate either two or three of the screws and spacers. Before you socket the Shield into the
Arduino, insert Phillips screws into the Arduino mounting holes that will fit.

mounting holes.
Slide the nylon spacers over the screws and then fit the Arduino onto the screws and Board of Education
Shield’s pins. After the Shield is firmly socketed, secure the screws with the nylon nuts. In the example
here, only two of three screws fit onto the Uno R3. The third screw could optionally be used without a
spacer; just be careful not to over-tighten it.
