## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR0812:1` (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/DFR0812:1.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-Saola-1 is a small-sized ESP32-S2-based development board. Most of the I/O pins are broken out to the pin headers on both sides for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-S2-Saola-1 on a breadboard.

ESP32-S2-Saola-1 is equipped with ESP32-S2-WROOM module, a powerful and generic Wi-Fi MCU module that has a rich set of peripherals. It’s an ideal choice for a wide variety of application scenarios like wearable electronics and smart home. The board has PCB onboard antenna, and 4MB SPI flash.
