## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0235:1` (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/SEN0235:1.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)

## Description

The DFRobot 360 degree rotary encoder module is based and designed on the EC11 rotary encoder button. The module has three signal terminals: terminals A & B are encoder output; terminal C is the button signal output. It is quite suitable for applications such as a volume knob and varying lighting voltage. The rotary encoder module comes with XH2.54 bonding pad, easy to use in prototyping projects such as automotive electronics, multimedia speakers, instrumentation, smart home and other fields.
