Customers have asked Adafruit to carry basic perf-board, but Adafruit never liked the look of most basic perf: its always crummy quality, with pads that flake off and no labeling...

## Pricing

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA589:1` (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/ADA589:1.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

Customers have asked Adafruit to carry basic perf-board, but Adafruit never liked the look of most basic perf: its always crummy quality, with pads that flake off and no labeling. Then Adafruit thought about how people **actually** prototype - usually starting with a solderless breadboard and then transferring the parts to a more permanent PCB. That's when Adafruit realized what people would really like is a proto board that makes it easy!
 
 This proto-board is the PCB you always wish you had, but never realized it! Adafruit took the basic layout of a quarter-sized breadboard (basically, a 'tiny' breadboard plus power rails) and turned that into a beautiful PCB. The top side has a white silkscreen, and the same markings you're familiar with, to make transferring components easy. The bottom has the 5-hole pad design that matches a classic breadboard, with 4 power bus lines on the sides, and no mask so you can easily cut traces when necessary. Adafruit used 1.2mm diameter drill holes so even parts with big leads will fit. All holes are **thru-plated for strength** - these wont peel off with rework. The finish is a gold plate - **you won't get oxidation like with bare copper perf**! There are also two mounting holes so you can attach the PCB to your project box.
 
 These are so handy, Adafruit decided to put them in a pack of 3. Once you use a Perma-Proto board, you'll never go back!
