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/EF08201:1.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 The Ring:bit Car Kit V2 is a small DIY smart car driven by the BBC micro:bit and the ELECFREAKS Ring:bit. It can be easily programmed to run autonomously, with a remote control, and even create rainbow beacons of light. Just add one of the many extensions available and your Ring:bit Car can do even more things like line and light following, obstacle avoiding, drawing, and more! Manual Installation: The ELECFREAKS Ring:bit Car is a small DIY smart car driven by the BBC micro:bit. Manual installation can better exercise a kid's hands-on ability. Ring:bit Expansion Port: The micro:bit Ring:bit car extends the micro:bit’s 3 GPIO ports(3 pins), allowing different sensors and components to be easily attached to the micro:bit. Creativity: Rich makecode graphical programming blocks allow kids to learn programming from the simplest to more complex. They can achieve making a shape, crazy dance, remote control, etc. ![microbit car kit](https://core-electronics.com.au/attachments/localcontent/290f65a9-5595-46b6-819d-bee33b0e3304_2146862b0f3.jpg)### | ![microbit robot kit](https://core-electronics.com.au/attachments/localcontent/9a9d8bc2-368f-461a-a929-a2830fa3bf6d_9864319c83a.jpg) | ![micro:bit car kit](https://core-electronics.com.au/attachments/localcontent/5bcbf3f8-35a0-4d7c-a097-861a4ec94ff5_759990b13f5.jpg) | ![micro:bit car kit](https://core-electronics.com.au/attachments/localcontent/88a93ff2-352d-4158-a5e2-f8dbe043d0ff_14171cbd2f4.jpg) | |---|---|---| | #### Tracking module Equipped with double infrared probes, it can accurately detect the distance between 2~12mm, which can achieve the function of line following around the circles, the detection of the black lines, and the detection of the edge. Note: You can additionally purchase our accessory modules on our website. | #### Sonar:bit module Sonar:bit is a 3-wire ultrasonic module with a working voltage between 3-5V. It is available to be used in 3.3V or 5V microcontroller systems. With only one 3-wire(GVS) cable, it can work properly. Compared to the standard 4-wire ultrasonic module, it has saved one IO port. The measurement range of sonar:bit is 4cm-400cm. It can output stable and accurate measurement data with ±1cm tolerance only. Note: You can additionally purchase our accessory modules on our website. | #### Light-bar module It can bring you multiple colors with simple assembling methods. It comes with 8 Rainbow full-color LEDs. You can update it to a car with auto-headlights and rainbow lights.
