Bittle X Platform + Pi Add-on

• Platform cover
• Pod body
• Top panel
• Button cap
• Logo inlays
• Camera mount

1. Install the “Bittle X” Cura profile. It sets 0.20 mm layers, no supports, and a 6-line brim.
2. Print each part in the orientation listed under Print settings. The STLs are already turned.
3. Print the panel from pod_panel.3mf, not the STL.

Tip The body walls are vertical, and the holes are teardrops. They print clean with no bridges.

• Platform cover
• Petoi Bittle X robot dog

1. Take the stock back cover off your Bittle X.
2. Put the platform cover on in its place. It fits the BiBoard and the touch sensor the same way.
3. The notch at the front left lets the head camera cable out.

• Pod body

1. Put the empty body on the four pegs, 7 mm behind its final place. The grille faces the rear.
2. Slide it 7 mm forward until it clicks.
3. The BiBoard header now sits in the notch at the front of the left well.

Tip To remove the body later, slide it 7 mm to the rear and lift it.

• Speaker, 3 W, 4 Ω

1. Push the speaker down into the two side grooves at the rear of the body.
2. The speaker body faces the rear grille.

• SPH0645 I2S MEMS microphone
• Dupont jumper wires

1. Plug the six jumpers onto the mic header. Use the 15 cm jumpers for GND and 3V.
2. Drop the mic into the slots on the right wall near the front. The port faces the wall and the header faces forward.
3. The panel holds the mic in place later. No tools needed.

• NS4168 I2S amplifier board

1. Plug the flat I2S cable into the front end of the amp, and the speaker into the rear end.
2. Put the bottom edge of the amp into the slot along the right wall, parts facing in.
3. Tilt the top edge under the two nubs, and set it with a drop of glue.
4. Let the amp cable hang out of the top for now.

• Raspberry Pi Zero 2 W
• PiSugar S battery board, 1200 mAh

1. Stack the Pi Zero 2 W on the PiSugar S with its screws.
2. Push the stack down into the two end grooves. Ports and the PiSugar controls face up. The SD card faces the rear.

• Dupont jumper wires

1. Follow the order and the pin table in Wiring above, from LineChef's guide. Plug one wire at a time.
2. Labels in the body show where each part goes: MIC, AMP, SPEAKER, BIBOARD, PIN 1, and PIN 40.
3. Push the BiBoard plugs onto the header at the front left last. All wires stay inside the body.

• Top panel
• Button cap
• Logo inlays

1. Press the post of the white button cap into the round hole in the panel tongue. Stop when the cap sits flat.
2. Glue the two logo inlays into the pocket in the front right corner: white at the left, red at the right.

• Top panel

1. Put the panel down 5 mm behind its place.
2. Slide it forward until the latch clicks. The hooks under the panel go under the lugs in the walls.

Tip To open: lift the rear edge at the finger notch, slide the panel 5 mm to the rear, and lift it.

• Camera mount
• Petoi AI Vision Module

1. Turn the camera mount 40° counterclockwise from its final place, seen from above.
2. Put it into the round socket in the panel with the two lugs through the keyways.
3. Turn it 40° clockwise until it clicks and stops.
4. Push the camera case down between the brackets, lens forward and USB port up, until the hooks click.

Tip To point the lens to the rear, turn the mount end for end first. It locks the same way.

• USB-C to micro-USB cable

1. Plug the USB-C end into the top of the camera.
2. Plug the micro-USB end into the Pi data port. The cable arches to the rear over the panel.
3. Charge the PiSugar, then press the large tongue on the panel to turn it on.
