PING)))TM Bracket Kit
(#570-28015)
The PING))) Bracket Kit includes a standard
servo and all mounting hardware required to
attach the PING))) ultrasonic sensor to the front
of the Parallax Boe-Bot®robot (or any custom-
made robot chassis with a flat mounting spot on
the front).
You may also purchase additional hardware
from Parallax to mount the HM55B Compass
Module to the same mounting bracket. That
hardware is not included in this kit but is
available from a hardware store or the Parallax
web site. See page 4 for more information.

Assembly Instructions
Step 1:
Enlarge two holes on the standard servo horn with a 3/32” (2.0
mm) drill bit or the tip of an X-Acto knife. Use caution in this
step since the servo horn plastic is quite brittle and can crack if
it is enlarged with a screw.

Step 2:
Attach the PING))) mounting bracket to the
servo horn using (2) 2/56 ¼” long screws
and nuts. Put the rubber grommet in the
bracket’s larger hole.
Step 3:
The mounting holes on the PING)))
mounting bracket accommodate both
Futaba and Hitec servo sizes and locations.
Identify the proper holes for your servo.
Step 4:
As viewed from the top, attach the PING)))
ultrasonic sensor to the PING))) mounting
bracket using (2) 4/40 ½” long screws, (2)
¼” long nylon spacers and (2) 4/40 nuts.
Step 5:
Disconnect power, then remove the Board
of Education®and four standoffs from the
Boe-Bot chassis. The Board of Education’s
front right mounting position will be used
for the straight bracket attachments; the
other one will mount on one of the
chassis’s front slots using a 4/40 ¼” screw
and nut. Install (3) nylon washers under
the other three standoffs and replace the
Board of Education on the chassis so it
remains level.

Step 6:
Attach the PING))) Mounting Bracket and
servo to the straight brackets using (4)
4/40 screws and (4) 4/40 nuts. Replace the
servo’s shaft screw once the PING)))
Mounting Bracket is installed.
Important: Before using the servo
screw, adjust the Ping))) bracket to
rotate 90°left and right.
Step 7:
Set the Servo Port Jumper on the Board of
Education to Vdd, then plug the servo into
servo port 14.
Note: If your board has no servo ports, or
no servo port jumper, or if you want to
keep the servos connected to Vin instead of
Vdd, follow the Breadboard Connection
section on page 3.
Step 8:
Connect the servo extension cable to the
PING))) sensor: Black to GND, Red to 5 V,
and White to SIG.
Plug the other end of the Ping))) sensor’s
cable into servo port 15.
You can download sample BASIC Stamp 2 source code and videos of
the Boe-Bot robot autonomously roaming with the Ping))) sensor
from the 570-28015 product page at www.parallax.com

Breadboard Connection
A breadboard connection will be necessary if you are using a
custom board/robot or any of the following boards with your
Boe-Bot robot:
•Serial Board of Education Rev A
•Serial Board of Education Rev B
•BASIC Stamp HomeWork Board
It is also useful if you have a servo port jumper, but wish to
keep your servos connected to Vin.
The PING))) sensor requires a 5 VDC power supply. To make the connections directly from the
breadboard:
1. Connect the servo extension cable to the PING))) sensor: Black to GND, Red to 5 V, and White to SIG.
2. Place a 3-pin male/male header in the other end of the cable, and plug it into the breadboard. Be sure to
position the cable where it won’t interfere with the sensor when the bracket rotates.
3. Using jumper wires, connect the Black lead to Vss, the Red lead to Vdd, and the White lead to I/O pin P15, as
shown.
Optional HM55B Compass Module Mounting Instructions
The Parallax HM55B Compass Module may also
be mounted on the bracket, on the backside.
The hardware for this, shown in the table at
right, is not included but may be obtained from
a local hardware store or ordered from
www.parallax.com.
Step 1: Mount the HM55B Compass Module on the back
side of the PING))) Mounting Bracket using (2) 4/40 ½”
screws, (2) 4/40 nuts and (2) 10” servo extension cables.
Step 2: Verify that your work matches the drawing
avove, that shows the back side of the PING)))
Mounting Bracket with an HM55B Compass Module.
Note: refer to the HM55B documentation for the schematic to connect your Compass Module to your
BASIC Stamp or other controller.
