## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0502:1` (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/SEN0502:1.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

**Introduction**

This looks like a potentiometer, but it’s an encoder switch.

It is a cascadable 360 ° rotary encoder switch with 20 pulses per revolution, and each pulse corresponds to a detent. There are LED lights set for each detent to allow users visually check the real-time status of the encoder.

For ease of use, the module is designed with I2C data output and configurable accuracy within 1~51 for every detent (set in the program). For instance, when it is set to 1, then you can turn on one LED light by rotating 2.5 revolutions; when set to 51, then one LED light can be switched on by rotating one detent.

In order to apply to more scenarios, the encoder is equipped with cascade function that enables to control multiple output devices by occupying only one I2C interface, such as, simultaneously controlling light brightness, color, volume, speed, etc.
