## Pricing

- **Price:** $27.20 (inc GST) — $24.73 AUD, exc GST
- **Quantity discounts:** 10+ $23.98 (exc GST) · 50+ $23.49 (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=ADA3904:1` (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/ADA3904:1.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

Make your next project super-flexy with a *biiiig* prototyping board that can [twist and shout](https://www.youtube.com/watch?v=cTaqn8_gMR0)– err, twist and bend! This passive flexible proto-PCB is about large as a piece of paper, but instead of dead-trees its made of very thin FR4.

Adafruit are not bending the truth! This protoboard is only 0.4mm thick, so its extremely bendable and [you can cut it easily with scissors](https://core-electronics.com.au/super-scissors-ph-51.html) - just don't use your nice fabric scissors since the fiberglass will dull them. It has a bend radius of about 2.5 cm (1") or better. You can also crease it, but that might break a trace if you crease a trace, and of course it may crack and break along the crease.

And, of course, there are 0.1" spaced prototyping holes with solder pads. They aren't fully plated through, the holes are only on one side. But, you can solder any thru-hole components to the pads. Sensors? LEDs? Jumper wires? Adafruit have no assumptions what people are going to use it for, but Adafruit know it is going to be **awesome**.

The PCB is really floppy. If you need to solder electronic components, you may need some physical support as the protoboard won't stay 'straight' on its own. So why not octopus it up and give yourself an extra hand (or four!) with some [Hobby Creek tools](https://core-electronics.com.au/search/?q=hobby%20creek)?
