## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA737:1` (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/ADA737:1.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

Imagine terminal blocks that are cut out of one solid piece of brass, designed to distribute power. Well, that's what Adafruit have here! These machined bus bars are for when you want to distribute power through a project, we think they are ideal for robots and LED pixel grids where you have tons of current and a lot of loose wiring to control
 
 Each bus has 7 holes bored out of a chunk of brass. There are screws that can cinch down any number of wires. Since its meant for power distribution, the wires should be 20 AWG or larger (thinner wires will slip out). You can use any larger wire, the holes are 6mm diameter! Adafruit don't have exact specifications for current carrying ability but Adafruit imagine they are good for at least 10A as its just a chunk of metal. Adafruit plan to use these for LED pixel matrix power distribution, which is a low voltage and fairly low amperage activity. If you want to use this for higher currents or voltages, please use common sense and plenty of testing until Adafruit can find a spec sheet!
 
 A nice touch on these is the plastic covering which provides a little isolation from the outside world, and mounting flanges.
