## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=FIT0973:1` (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/FIT0973:1.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

This is an M.2 M Key to PCIe3.0x16 graphics card extension cable specially prepared for [LattePanda Sigma](https://core-electronics.com.au/lattepanda-sigma-x86-windows-linux-single-board-computer-server-32gb-ram.html?123) users. It has a PCIex16 card slot, a differential signal hole-free design, and no signal attenuation and interference problems in parasitic capacitance and parasitic inductance. No driver installation is required, just plug and play. It can be easily paired with an external graphics card or PCIe device on the Sigma motherboard to maximize LattePanda Sigma's performance.

We use metal-shielded wires and advanced EMI-shielding conductive polymers to ensure the stability of signal transmission. At the same time, we use new materials for EMI shielding to make the wire design flatter and can be bent and folded without affecting the use experience.

In addition, the adapter card also supports independent power supply and is equipped with a 15-pin SATA power cord, which eliminates the trouble of additional wiring and is more convenient to use.

**Note:**

1\. Be sure to know the direction when plugging in the wire, and do not plug it in backwards or out of position to prevent burning the device. When plugging in, hold the socket of the device before plugging in the cord to avoid using too much force to disconnect the socket pins. Do not bend or pull within 2cm of the welding point between the two ends of the wire and the circuit board.

2\. Depending on the signal drive capabilities of various motherboards and devices, the signal may experience attenuation when an extension cable is connected.
