What to buy first

Start with the missing matched USB audio parts. Do not buy duplicates: mark what you own or have ordered below. The current PF1 build is stationary.

Ownership starts unknown and saves only in this browser. It is never published as your order history.

1 · Buy first, only if missing

Seeed reSpeaker Lite USB 2-Mic Array, 107990273, without XIAO or case

Required: 1 · Buy only what is missing

Microphones and speaker audio interface for the stationary Pi 5 bench.

USB firmware version; received board revision and hole layout still require measurement before PC1 mounting. Do not substitute a Pi HAT or XVF3800.

Manufacturer specification

Seeed Mono Enclosed Speaker 4 ohm 5 W, 114993346

Required: 1 · Buy only what is missing

Matched voice-output speaker for Lite.

Inspect attached connector and polarity against Lite before connecting; do not force. Received ear dimensions and grille clearance need checking. The body mount has an unresolved 38 mm nominal grille/cassette/shell through-bolt stack; this does not block supported bench audio. No separate amplifier specified.

USB-A to USB-C data cable; selected candidate Seeed 106990248, 1 metre

Required: 1 · Buy only what is missing

Pi USB-A to Lite USB-C carries data and power.

Reuse a known-working cable. Charging-only cables are unsuitable. Keep the audio USB disconnect reachable. Final plug envelope and routing must be checked; this is not the Pi power supply.

2 · Reuse or borrow these tools first

Digital caliper with millimetre readout

Required: 1 · Buy only what is missing

Measure nuts, screw stacks, speaker ears and printed clearances before fit-dependent purchases.

Borrow/reuse first. Check zero and repeat critical measurements. No model or offer selected.

Compatibility sources and buying reference

Amazon search phrase: digital caliper millimeters

No specific product or current offer selected. Resolve the fit/specification before buying.

Drivers and nut tools matching the actual screw heads

Required: 1 · Buy only what is missing

Dry-fit and assemble without damaging small fasteners.

Check screw heads before buying a tool set; M2/M3/M4 describe threads, not driver sizes. Reuse suitable tools.

3 · Camera comes later

Raspberry Pi Camera Module 3 Standard, IR-cut; SC0872 candidate

Required: 1 · Buy only what is missing

Adds local vision after audio tests.

Standard only, not Wide or NoIR. Body installation remains held: three of four camera nut pockets have obstructed access. It can be purchased for a separately supported bench test, but purchasing does not qualify the PC1 mount. Verify package SKU.

4 · Wait for measurements or a released design

Official Raspberry Pi Camera Cable Standard–Mini; length after route measurement

Required: 1 · Buy only what is missing

15-pin camera to 22-pin Pi 5 connector.

200 mm is the existing near-Pi bench candidate, not a verified body-route length. Measure a relaxed service loop. CAMERA cable only; display cables are not interchangeable. Connect only with Pi power disconnected.

Pi case restraint hardware / nonconductive pads

Required: not specified yet · Buy only what is missing

Secure the actual Pi case to the stationary tray.

Measure actual case, ports, cooling clearance and tray first. The 180 x 140 mm tray is a design envelope, not measured case fit. No loose powered case.

No specific product or current offer selected. Resolve the fit/specification before buying.

Cable edge protection and strain relief

Required: not specified yet · Buy only what is missing

Protect USB and camera ribbon at actual body openings.

Choose grommets/clamps only after measuring openings, panel thickness, plug passage and cable path. Avoid ribbon pinching and keep audio disconnect accessible.

Compatible filament for approved fit coupons / replacement parts

Required: not specified yet · Buy only what is missing

Produce only qualified parts and requested prototypes.

Inventory usable material first. Exact material/profile and total spools require the current printer, coupon qualification and actual sliced mass. Do not infer one spool completes the robot.

Motors, motor mounts, wheels/hubs/caster and motor controller

Required: not specified yet · Buy only what is missing

Future moving version, outside current stationary PF1 build.

No released current selection or quantity. A robot-car kit is not required for the current build. Any future mobility design must establish shafts/mounts, mass/load, torque, voltage, measured stall current and independent drive-stop design together. Historical Pololu parts are not a PF1 order list.

No specific product or current offer selected. Resolve the fit/specification before buying.

Battery, matched charger, power wiring, fuse/distribution and drive-stop hardware

Required: not specified yet · Buy only what is missing

Future reviewed mobile power system.

No pack chemistry, voltage, connector, capacity, fuse, wire gauge or cutoff rating released. Do not buy speculative battery parts or use the Pi bench supply as a motor supply.

No specific product or current offer selected. Resolve the fit/specification before buying.

5 · Optional later

Physical push-to-talk button and capture/status indicators

Required: not specified yet · Buy only what is missing

Physical controls after the local software bench works.

Switch/LED electrical specifications, protective circuit and PC1 cutouts are not selected. Use deliberate local software controls first. Indicator lighting alone is not proof of privacy.

Compatibility sources and buying reference

No specific product or current offer selected. Resolve the fit/specification before buying.

Thin compliant speaker pad / acoustic gasket

Required: not specified yet · Buy only what is missing

Only if a fitted speaker rattles or needs sealing.

Thickness changes fastener stack and cone/grille clearance. Choose only after the fit test; not a default purchase.

These three parts work together by USB. Reuse an exact part or known-working data cable you already have.

A charging-only cable will not work. Do not assume a cable comes with the Lite board.

Manufacturer evidence

$31.49 observed audio-item subtotal using the $26.99 California Lite observation + $2 speaker + $2.50 cable. Not a checkout quote; current generic Lite price differs. Shipping, tax and duties are not included.

Need a safe support for the audio board?

Optional, one only: Seeed acrylic enclosure 110991984 · $5 observed. It holds Lite and its matched speaker for bench use. Use the included hardware and official assembly video. It does not replace the later MORLOK body. Skip it if you already have a suitable stable, nonconductive board support.

The speaker’s earlier selected China-stock notice said dispatch from 6 October, UPS from 7 October. This is not a delivery promise; parts may ship separately.

2. Add the camera

Two items, one of each. The cable included with many camera kits is the wrong width for the Pi 5 end.

Check this before ordering

Only this 200 mm Standard–Mini camera cable is the first-bench choice. Later body routing may need a different length; do not buy multiple lengths now.

Manufacturer evidence

Do not add these to this basket

Pico, motors, wheels, hubs, caster, drivers, battery, charger, motor-power protection, structural deck and full shell fasteners are later mobility work. No separate microphone switch, amplifier, Pi or robot-car kit is needed for this bench.

The small camera-shutter print is tracked separately. Final screws and fitted mounts depend on the real parts, not this shopping list.
