## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=TEL0109:1` (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/TEL0109:1.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

WT8266-S1 Wi-Fi module is a low consumption, high-performance embedded Wi-Fi network control module designed by Wireless-Tag. It can meet the IoT application requirements in smart power grids, building automation, security and protection, smart home, remote health care etc. 

The module's core processor ESP8266 integrates an enhanced version of Tensilica's L106 Diamond series 32-bit processor with a smaller package size and 16 bit compact mode. Main frequency supports 80 MHz and 160 MHz, supports RTOS, integrated Wi-Fi MAC / BB / RF / PA / LNA, on-board PCB antenna. The ESP8266 WiFi Module is a self-contained SOC with an integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network.

The module supports standard IEEE802.11 b / g / n protocol, a complete TCP / IP protocol stack. Users can use the module to add networking capabilities for existing equipment, also can build a separate network.
