When a Sprint Helps
- You know the part class but not which channel to trust.
- Two listings disagree on variant or kit contents.
- You need price, MOQ, lead time and warranty confirmed before a purchase order.
A desk review, not a guarantee. Work starts only after the scope is accepted in writing; payment details follow acceptance.
The Evidence You Get
Six pages in a fixed format, shown on the same hypothetical LiDAR case. On a phone, each supply path opens as a card.
Sourcing Sprint
FORMAT SAMPLE / INDOOR MOBILE ROBOT / 360° 2D LiDAR
Supply options for one hardware requirement, compared on public evidence — with every unknown left visibly open.
FORMAT SAMPLE — NOT A COMPLETED CLIENT DELIVERY. No supplier was contacted. No quotation, MOQ, lead time, stock, authorisation or partnership was obtained. Three sourcing paths are shown, not three contracted suppliers.
Your target
What the buyer asked for, and what is still missing before any supplier can be asked a useful question.
| Item | Recorded | Status |
|---|---|---|
| Category / variant | 360° 2D LiDAR, UART with USB bridge | variant open |
| Quantity | 1 prototype; later small batch | range to confirm |
| Destination | — | missing |
| Delivery constraint | — | missing |
| Must-have | Indoor 2D navigation; dark-obstacle detection near the robot | recorded |
| Host / ROS | Raspberry Pi-class; ROS 2 desired, distribution unknown | missing version |
Missing before outreach
- Ship-to country and buyer of record
- Exact ROS 2 distribution and host OS
- Quantity bands (1 / 5 / 20) and target date
- Acceptable kit contents (adapter, cable, mount)
Supplier evidence ledger
Manufacturer, distributor and retailer are different supplier types. Nothing is labelled “authorised” without documentary proof.
| Sourcing path | Role (verified) | Source | Variant evidence | Identity / document check |
|---|---|---|---|---|
| SLAMTEC (manufacturer) | Manufacturer | S1 public spec page | RPLIDAR C1; range conditional on reflectivity; TTL UART | Identity from official site; regional distribution not checked |
| Waveshare (retail kit) | Retailer / kit supplier | S3 · S4 | D500 LiDAR Kit listing with kit contents | Reseller rights and kit revision not established |
| SLAMTEC (alternative product) | Manufacturer | S2 public spec page | RPLIDAR A1; 5.5 Hz; 0.15–12 m; UART 3.3 V | Only if the buyer accepts a lower scan rate |
The Waveshare D500 LiDAR Kit is not proven identical to TANNAI TR-LID-D500. A shared model fragment is not evidence of OEM origin, kit contents or certification equivalence.
Commercial matrix
No generic zeroes and no guessed numbers: a term is filled only from a dated public listing or a written supplier reply.
| Term | Path A · C1 | Path B · D500 Kit | Path C · A1 |
|---|---|---|---|
| Exact SKU + kit contents | Variant to confirm | Listed: kit, adapter, USB A–Micro USB cable, 4-pin cable — confirm revision | Variant to confirm |
| Published reference price (currency, date) | needs supplier confirmation | needs supplier confirmation | needs supplier confirmation |
| MOQ / volume price | needs supplier confirmation | needs supplier confirmation | needs supplier confirmation |
| Lead time + dispatch location | needs supplier confirmation | needs supplier confirmation | needs supplier confirmation |
| Incoterms + shipping | needs supplier confirmation | needs supplier confirmation | needs supplier confirmation |
| Taxes / duties | needs supplier confirmation | needs supplier confirmation | needs supplier confirmation |
| Warranty + DOA | needs supplier confirmation | needs supplier confirmation | needs supplier confirmation |
| Returns | needs supplier confirmation | needs supplier confirmation | needs supplier confirmation |
| Sample availability | needs supplier confirmation | needs supplier confirmation | needs supplier confirmation |
Risk decision
Each rating is explained in words rather than with a pseudo-precise score.
| Risk | Rating | Why |
|---|---|---|
| Compatibility / package mismatch | Open | Kit revisions and bridge boards differ; ROS 2 driver not verified for the buyer host |
| Warranty ownership | Open | Who honours warranty for a retail kit shipped abroad is not documented |
| Channel authenticity | Open | Retail listing is public; reseller status relative to the manufacturer is not established |
| Logistics / country | Open | Destination unknown; duties, battery-free shipping and returns address unconfirmed |
| Supplier response | Unknown | No outreach has been made; responsiveness cannot be rated |
| Document coverage | Partial | Specifications are public; commercial terms are not |
Action plan
A preferred follow-up based on the buyer's constraints — not a guaranteed recommendation.
Supplier question script (for approved outreach only)
- Quote exact model + revision, SKU, full kit BOM, quantity 1 / 5 / 20, currency, price validity and payment terms.
- Confirm stock / lead time and dispatch location in writing.
- Confirm authorised distribution status only if relevant, with proof.
- Provide package contents, current datasheet, SDK / ROS driver versions, interface and power documentation.
- Confirm shipping to the buyer country, Incoterms, duties handling, warranty, DOA terms and return address.
- Confirm the right to reproduce images / spec sheets if the buyer needs them.
Proceed-to-PO gates
- Buyer constraints complete (destination, quantity, ROS version)
- Written quotes for the exact variant from at least one path
- Sample plan agreed, if a physical check is needed
- Warranty, returns and seller of record confirmed
- Only then: purchase order

Does US$590 buy products?
No. It pays for scoped sourcing research and a written report.
Does it include three manufacturer quotes?
No. Verified replies appear only when independently obtained and permitted. We never invent them.
Do you represent specific brands?
No status is implied unless it is separately documented.
Which markets can you cover?
We first confirm whether the destination and category are serviceable.
What about tariffs and duties?
They are listed as purchase questions; legal and tax advice is not included.
Can I upgrade from the Fit Review?
A single documented pilot credit can be considered once final terms are approved.
