## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR0814:1` (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/DFR0814:1.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**ESP32-S2-MINI-1 is a powerful, generic WiFi-MCU module that has a rich set of peripherals. It can be applied in a wide variety of scenarios relating to wearable electronics, smart home, etc.

The module embeds ESP32-S2FH4 chip, an Xtensa® 32-bit LX7 CPU that operates at up to 240 MHz, and features a PCB antenna.

The chip has a low-power co-processor that can be used instead of the CPU to save power while performing tasks that do not require much computing power, such as monitoring peripherals state change or whether an analog value exceeds the threshold.
