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/DFR0963:1.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) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description This is an embedded serial-to-Ethernet module based on the ESP32 series, also can be called a gateway. **The module integrates an optimized TCP/IP protocol stack**, which is convenient for users to easily complete the networking functions of embedded devices while reducing development time costs. The ESP32 series of ICs are SOCs that integrate 2.4GHz Wi-Fi and Bluetooth dual-mode, with ultra-high radio frequency performance, stability, versatility, reliability, and ultra-low power consumption. The module has diverse and powerful functions. It supports four working modes: TCP Server, TCP Client, UDP Server, and UDP Client; supports serial port, WiFi, Ethernet, and Bluetooth four data ports for pairwise combination, and 6 data transparent transmission modes; supports WiFi to connect to the Internet or local area network through a router, establish a TCP/UDP connection, and access the user's designated server.; support user's secondary development based on ESP32. ![Embedded Serial to Ethernet Module](https://core-electronics.com.au/attachments/localcontent/1_45749230a70.jpg) The module can be used in agriculture, industry, medical equipment, and other fields. It is an excellent choice for data transmission in IoT scenarios, such as smart agricultural sensor data monitoring. The module can collect and transmit data from sensors such as air temperature and humidity, soil temperature and humidity, soil PH value, and carbon dioxide concentration to the server. The module has abundant IO ports, which can realize the functions of temperature acquisition and mutual control of ventilation and heating equipment. **Note:** The applicable temperature of the product is -20°C~+70°C ### Features 10.
