Pre-Release Schematic

Just a quick little update to let you know that I uploaded the schematic for our current pre-release board to Piunora's hackaday.io project page. We thought it might help answer some of the questions that our more curious users have been asking. Read the full update.

Prototyping Can Be Fun & Easy!

There are some really cool things you can do when you combine an electronics dev board with a Linux SoC! Today, I want to show you how easy it is to prototype with Piunora by making a sensor-based game controller. In the demo below, we are using Adafruit Blinka (a library that enables CircuitPython code on Linux) and an Adafruit VCNL4040 distance sensor attached by a single cable to Piunora's Qwiic/Stemma-QT connector. No breadboards or soldering required! Read the full update.

Introducing the Piunora M.2 B-Key 2280 Extender

I have received a lot of requests for ways to support long, 2280 M.2 devices. While Piunora is small—and therefore only supports up to 2242 devices in its native form factor—I love seeing people come up with cool hacks, and I want to help out however I can. (One such request was for a PCI-e-to-4x-RS232 adapter. Who knew that was even a thing!?) Anyway, in response to these requests, I have added an adapter board to the campaign. Read the full update.

It Begins!

I'm excited to announce that the crowdfunding campaign for Piunora has begun! This has been a thrilling journey for me. It all started with a little weekend project back in December 2020 that ended up with me starting a side business—Diodes Delight—and developing Piunora into a real product. Read the full update.

$39

Piunora Pro

A compact, feature-rich CM4 carrier board


$30

Piunora Lite

Perfect if you need the slimmest possible form factor. Includes all features of Piunora Pro except for the camera connector and the PCI-e M.2 port.


$14

M.2 B-Key 2280 Extender

Expands Piunora's M.2 port to accommodate full-length 2280 peripherals. Keep in mind that such devices are quite a bit longer than Piunora itself, so they might look a little awkward hanging off the end there. But, if you have a cool idea that depends on a 2280 M.2 accessory...this is the product for you.


$37

Raspberry Pi CM4 (Lite, Wireless, 1 GB RAM)

From the Crowd Supply Basics project.

Something for your Piunora to carry.

This CM4101000 variant of the Raspberry Pi Compute Module 4 is a System on Module (SoM) containing an ARM quad-core Cortex-A72 processor, 1 GB RAM, 2.4 and 5 GHz 802.11b/g/n/ac Wi-Fi and Bluetooth 5.0, and supporting power circuitry. Does not include eMMC flash.


$49

Raspberry Pi CM4 (8 GB eMMC, Wireless, 2 GB RAM)

From the Crowd Supply Basics project.

Something for your Piunora to carry.

This CM4102008 variant of the Raspberry Pi Compute Module 4 is a System on Module (SoM) containing an ARM quad-core Cortex-A72 processor, 2 GB RAM, 2.4 and 5 GHz 802.11b/g/n/ac Wi-Fi and Bluetooth 5.0, 8 GB eMMC flash, and supporting power circuitry. With this eMMC variant of the CM4, the SD Card interface is not usable.


$15

Heatsink for CM4

You can operate the CM4 without a heatsink just fine, but if you have some extra-heavy computation to do, then a heatsink can help prevent thermal throttling of the SoC. Includes a mounting footprint for a 30 mm fan (not included) should you want to integrate it into an enclosure or take your CM4 to even greater extremes of computation. Also includes a set of stacking pin headers to accommodate expansion boards.


$10

microSD Card

From the Crowd Supply Basics project.

Boot media for the "Lite" (CM4101000) variant of the CM4. We recommend 64 GB or smaller.

An industrial-grade memory card with extended endurance.
