**Type:** Product page · **SKU:** AC-B0302 · **Brand:** [Arducam](https://core-electronics.com.au/brands/arducam-australia)
**Page:** https://core-electronics.com.au/arducam-pico4ml-tinyml-dev-kit-rp2040-board-w-qvga-camera.html ([markdown](https://core-electronics.com.au/arducam-pico4ml-tinyml-dev-kit-rp2040-board-w-qvga-camera.html.md))

Arducam team took the Raspberry Silicon - the RP2040 and created Pico4ML. A microcontroller dev board for embedded machine learning.

> ⚠ Deal is for shelf stock only — any additional stock will be at the normal price.

## Pricing

- **Price:** $36.51 (inc GST) — $33.19 AUD, exc GST

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 4 today; more stock is typically available with a 14–17 day lead time.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=AC-B0302:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/AC-B0302:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)
