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/ADA4354:1.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) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description Adafruit put a PermaProto full-sized proto board in a blender with a Pi Cobbler and out emerged this very tasty confection - the 40-Pin PermaProto for Pi! It has the Cobbler baked right in. Simply solder the 2x20 box header in, and you get all the labeled breakouts with tons of prototyping space, power rails, mounting holes and that gorgeous silk. **This version is for modern Raspberry Pi computers with 2x20 connectors such as the Pi B+, A+, 2, 3, 4, Zero, etc!** [They also stock a version for the older Pi 1's with 2x13 headers.](https://core-electronics.com.au/adafruit-perma-proto-raspberry-pi-breadboard-pcb-kit.html) Customers have asked Adafruit to carry basic perf-board, but Adafruit never liked the look of most basic perf: it's 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 full-sized breadboard (the PCB has 60 rows instead of 63 rows) 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 won't peel off with rework. The finish is a gold plate - **you won't get oxidation like with bare copper perf**! There are also tons of mounting holes so you can attach the PCB to your project box. Comes as one PCB and one box header. You'll need to do a little soldering to attach the box header to the PCB. but it's fast and easy to do. To connect a Pi, you'll also need [a 40-pin GPIO cable](https://core-electronics.com.au/gpio-ribbon-cable-for-raspberry-pi-model-b-40-pins.html), if you don't already have one. ## Technical Details - 20 x dual rows 4-pin holes breaking out the GPIO cable - 2 x dual rows of 4-holes - 38 x dual rows of 5-holes - 4 power rails with positive/negative markings - 6.2" x 2.0" (160mm x 50.8mm), 0.063" thick FR4 - 1.2mm / 0.047" drill holes [EagleCAD PCB files on GitHub](https://github.com/adafruit/Adafruit-Perma-Proto-Pi-PCBs) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/4/3/4354-03.jpg)
