## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=DFR0940:1` (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/DFR0940:1.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 Raspberry Pi Power Filter Board integrates multiple solid capacitors, ceramic capacitors and tantalum capacitors to perform parallel hybrid filtering.

**It can filter low-mid-high frequency power supply noise, which provides the whole system with a more stable power supply and increases sound quality.**

Connect the module directly to the Raspberry Pi's GPIO port for easy setup. When combined with an audio decoder board, the Raspberry Pi is transformed into a high-quality stereo system.
