Assembling Pi2Go

pi2go_01a

Pi2Go is the pre-soldered big brother of the popular Pi2Go-Lite kit. Assembly is simply a matter of screwing together and plugging connectors.

Overview of Steps

  1. Fit the front caster and line following assembly
  2. Fit the mounting pillars for your chosen Raspberry Pi
  3. Attach the motors
  4. Fit the Raspberry Pi
  5. Fit the battery box

 

Step 1 – Fit the Front Caster and Line Follower Assembly

Step01

You will need the M3 screws, 27mm pillars, ball caster and 9-way extended header and the line follower PCBA

Step02

Fit the 2 pillars to the front of the Pi2Go using 2 of the M3 screws

Step03

Carefully push in the 9-way header, then attach the line follower PCBA

Use the remaining 2 screws to attach the ball caster. If there is a bit of slack in its position, ensure that it doesn’t touch the pins of the connector

 

Step 2 – Fit the Mounting Pillars for Raspberry Pi

For the older Raspberry Pi models with a 26-pin GPIO connector, you will need to fit 2 pillars. For the A+, B+ and RPi 2B you should fit 4 pillars

Step04

Fitting the pillars is a 2 step process: 1) fit the small 5mm pillars, 2) screw in the 16mm pillars.

Step05

The photo above shows the 5mm pillars in the mounting positions for A+, B+ and RPi 2B models

Use the very small 4mm screws to attach all the pillars. Note that the holes under the motors have been countersunk to allow the motors to sit flat onto the PCBA

Step06

The photo above shows the 16mm pillars added for the correct height (A+, B+, RPi 2B)

Step06a

The photo above shows the 2 pillars in place ready for the Model A or Model B

 

Step 3 – Attach the Motors

Step07

For this you will need 25mm screws, nuts and the motor mounts

Step08

Push the screws through the outer motor mount, then the motor, then the inner motor mount and attach to the nuts

Step09

 

Step 4 – Fit the Raspberry Pi

Step10

Using the extended header (in the bag with the battery box), connect the Pi onto the Pi2Go PCBA.

NB. Ensure that the mounting holes line up with the pillars! If they don’t then the Pi is not fitted correctly and may be damaged.

The above photo shows the RPi 2B in place. The A+ and B+ fit the same way.

Step10a

This photo (above) shows a Model B

 

Step 5 – Fit the Battery Holder

Step11

Use the 5mm pillars to attach the Raspberry Pi firmly to the mounting pillars. Use 2 or 4 pillars depending on your model of Pi (RPi 2B shown above)

For the Model A and Model B, you can now screw the battery holder directly to the 2 supporting 5mm pillars

Step12

For the A+, B+ and RPi 2B you will need to fix the support plates in place first

Step13

Ensure the one at the front has the threaded insert on the left of the Pi2Go and the one at the rear on the right. Also ensure that the wide parts of the mounting holes are at the top so that they can accept the heads of the screws.

Step15

Finally, screw in the battery holder using 2 of the very small 4mm screws

Now you can add batteries, software and enjoy!
