Components & Beta Testers

by Timon

Our project was fully funded, and we even exceeded our goal! Thank you so much to everyone who backed the campaign. It means a lot to us!

We’ve been very busy over the past few weeks, buying all of the components for the first batch of Piunoras. Initially, it was looking like we might be facing considerable delays due to component shortages, but we managed to secure all of the components we need by finding drop-in replacement for parts that were out of stock.

It will still take a few weeks to get all of those components together, but having them all secured is a major milestone on the manufacturing side of things. The hardware industry is in rough shape right now, with many small manufacturers facing backorders well into 2022 and struggling to get the components they need. So we’re feeling very fortunate to have secured this first batch, though it might look worse for subsequent manufacturing runs, as these is currently no end in sight to these supply-chain issues.

In the meantime, all of my reviewers have received their units and have gotten started putting Piunora to the test! You can check out what Les Ponders from Tom’s Hardware is doing with his Piunora in this Twitter thread: https://twitter.com/biglesp/status/1396042377983315968

Also, have a look at this lovely pic of Piunora + Cat from bleeptrack: https://twitter.com/Bleeptrack/status/1393524279162155008

We are on track so far, but delays are still very possible. Our next hurdle is to make the very last design revision and verify it with our manufacturing partner. We’ll keep you all updated with any progress!

Product Choices

$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.


$7

RPi CM4 Wi-Fi Antenna Kit

From the Crowd Supply Basics project.

An omnidirectional 2 dBi gain 2.4/5 GHz Wi-Fi antenna with panel-mounting hardware and an approximately 7.5" (19 cm) cable to connect the antenna's SMA connector to the CM4's U.FL connector. It is "certified for use with the Raspberry Pi Compute Module 4".
