- **Quantity discounts:** 10+ $96.95 (exc GST) · 50+ $94.95 (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=ADA5404:1` (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/ADA5404:1.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

**Piunora** by **[Diode Delights](https://www.diodes-delight.com/)** is a compact, easy-to-use development board for electronics prototyping with Linux. It has a familiar form factor, legible pin labels, and a design that’s well suited to space-constrained applications.

As a carrier board for the Raspberry Pi Compute Module 4 (CM4), Piunora is essentially a tiny version of the Raspberry Pi 4 Single Board Computer (SBC) with added flexibility to accommodate custom form factors. CM4-based devices like Piunora are fully compatible with software that was written for the Raspberry Pi 4, as long as that software accounts for the hardware peripherals in use. There are also versions of the CM4 that include eMMC memory, which is more reliable than a traditional SD card.

It may be small, but Piunora is packed with powerful peripherals!

## Features & Specifications

- Arduino UNO R3 / Adafruit Metro compatible form factor (3.3 V logic, may not be compatible with all Shields)
- PCI-e through M.2 B-Key connector on the rear of the board with dedicated 3.3 V / 3 A supply
- Analog to Digital Converter (MCP3008)
- On-the-fly switching between USB host (USB Type-A) and device mode (USB Type-C)
- Qwiic/Stemma QT connector to easily interface with I²C devices
- A full-sized camera connector that supports all Pi-compatible cameras
- A full-sized HDMI 2.0 port
- A WS2812 Smart RGB LED for user status
- Optional Wi-Fi or eMMC options depending on your choice of CM4
- Slim design with the Piunora Lite measuring 8-12 mm and the Piunora Pro measuring 11-13 mm
- Two user-controllable buttons (including software that turns one of them into a safe-shutdown button)
- Open hardware. Design files and software are published by the time it ships
 
**Pi 4 Compute Module is not included**, [but We carry them here](https://core-electronics.com.au/raspberry-pi/boards/compute-module-4.html).

Don't need as many extras? Piunora Lite uses the exact same PCB as Piunora Pro but leaves off the bottom side components for space and cost savings.
