## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR0778:1` (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/DFR0778:1.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.)

## Description

This industrial-grade RS232 shield from DFRobot is specially designed to expand one RS232 port (D-Sub, 9Pin, male) with high reliability for [LattePanda Alpha](https://core-electronics.com.au/lattepanda-alpha-8g-64gb-tiny-ultimate-windows-linux-device.html) and [LattePanda Delta](https://core-electronics.com.au/lattepanda-delta-4g-32gb-win10-pro-activated-tiny-ultimate-windows-linux-device-pre-order.html). Employing FTDI USB to serial port chip and industrial-grade isolated transceiver module, the shield comes with the characteristics of signal isolation, power isolation, lightning and surge protection, transient impulse voltage resistance, and bus protection so that it supports reliable data transmission and also can effectively protect your LattePanda mainboard for providing a high-reliability connection for point-to-point.

The product employs a stackable connection, making it able to be easily fixed onto LattePanda mainboard by copper columns without blocking the heat dissipation area of the mainboard. It can be safely applied in industrial scenarios.
