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/POLOLU-5006:1.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) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description | [![](https://core-electronics.com.au/attachments/localcontent/0J11319_4468532490a.jpg)](https://core-electronics.com.au/attachments/localcontent/0J11319_81768b8d61d.jpg) | |---| The 3pi+ 2040 Control Board is designed to be assembled with a [3pi+ Chassis Kit](https://core-electronics.com.au/3pi-chassis-kit-no-motors-or-electronics.html), a pair of 6V [Micro Metal Gearmotors with extended motor shafts](https://core-electronics.com.au/category/141/micro-metal-gearmotors-with-extended-motor-shafts), and a [graphical OLED display](https://core-electronics.com.au/graphical-oled-display-128x64-1-3-white-spi.html) to create a 3pi+ 2040 robot.
