## Pricing

- **Price:** $1.55 (inc GST) — $1.41 AUD, exc GST
- **Quantity discounts:** 10+ $1.36 (exc GST) · 50+ $1.34 (exc GST)

## Availability & dispatch

- Out of stock — the product page offers email notification when it returns.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA2211:1` (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/ADA2211:1.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

Keep your microcontroller or real-time-clock tickin' with a a fancy timing crystal. This 32.768 KHz model comes in a cylindrical style standard package and is breadboard friendly and easy to use with any microcontroller, RTC or device that requires an external crystal.

The crystal has 12.5pF load capacitance requirements and is ideal for use when you have a real-time clock or other ultra-power chip.

To use, connect the two pins to XTAL-in and XTAL-out on your circuit (the package is symmetric so use whichever pin). Check your microcontroller datasheet in case you also need a 1 Megaohm resistor or any other components, usually 32.768KHz crystals do not require capacitors.
