MINI BOT
Assembly Guide to SparkFun’s ProtoSnap MiniBot
The ProtoSnap MiniBot is the newest addition to SparkFun's line of
ProtoSnap products. The MiniBot is a complete robotics platform that
allows you to build a small, wheeled robot using the included parts and your
own tools. The MiniBot can be used in conjunction with the Arduino
programming platform, allowing you to program the platform to suit your
individual needs.

Soldering Tips
Don’t: Glob the solder straight onto
the iron and try to apply the solder with
the iron.
Do: Use a sponge to clean your iron
whenever black oxidization builds up
on the tip.
Do: Touch the iron to the component
leg and metal ring at the same time.
Do: While continuing to hold the iron in
contact with the leg and metal ring,
feed solder into the joint.
Quick Soldering Tips:
Required Tools:
Soldering Iron Wire Cutters
(not included in kit)
Don’t: Use the very tip of the iron.
Do: Use the side of the tip of the iron, “The Sweet Spot.”

Start Here: Your First Component
Push the legs through the board until the
component is flush with top side.
3
Bend legs outward to keep in place.

Locate the silkcreen footprint on the board and place transmitter through the board.
Make sure the lens bump faces foward.
Flip the board over. Hold the soldering
iron’s “Sweet Spot” so it touches both the
leg and the metal ring. Hold for 2 seconds.
5
Your solder joints should look like this -
a tiny volcano.
8
Clip off any excess legs.
9
Feed solder into the joint.
6
Pull solder away first. Then iron next.

Locate the silkcreen footprint and place the second transmitter through the board.
12
Repeat the same process to solder the second transmitter
flush to the board. After you complete this the board should
now look like the image below.

* The receiver needs to sit higher than the transmitter.

14
Locate the silkcreen footprints on the board for each receiver.
15
Solder the two receivers so they sit just higher than the
transmitters. If there isn’t enough clearance in heights they
will not work properly.
*The receiver is color coded red.

Locate the silkscreen footprint for the battery holder. Follow the
directions on the next page. Use the illustration below for reference.

Congratulations! You’ve successfully soldered the infrared
components. Now use the same method to place and solder
the rest of the components in the kit!
BE CAREFUL, THE FOLLOWING STEPS INVOLVE THE TOP AND BOTTOM SIDE OF THE BOARD.
THIS ARROW INDICATES WORKING ON THE TOP SIDE OF THE BOARD.
THIS ARROW INDICATES WORKING ON THE BOTTOM SIDE OF THE BOARD.
THIS ARROW INDICATES LOOKING AT THE BOARD FROM THE SIDE.
17
Peel one side of the the double stick tape in
the center of the footprint. Once placed, peel
off the top side to prepare for the battery
holder.
18
Place the battery holder on top of the tape.
This will hold it in place as you solder it in
from the bottom side.
*Be sure to align the battery holder with the positive (+)
and negative (-) markings.
19
Flip the board over and solder. You will need
more solder than you used in the earlier
steps. Be liberal in feeding solder until
completely full.
20
Your solder joint should look like this.

Locate the footprint for the gearbox on the bottom side of the board. Use
the screws and nuts that came with the gearbox to secure into place. Then
place the tires onto the axle if you have not done so already.
For this kit you will need to assemble the gearbox first. You can
find the directions for the gearbox inside the Tamiya box.
It is important that you assemble the instructions marked “A”.
