Introducing the Piunora M.2 B-Key 2280 Extender

by Timon

First off, thank you for all the support over the past few days. It really means a lot!

M.2 B-Key 2280 Expander

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.

The Piunora M.2 B-Key 2280 Extender (shown above) allows you to utilize M.2 devices up to 80 mm in length. Please note that this is still a B-Key port! Also, the adapter is quite a bit longer than Piunora itself, so it looks a little awkward when it’s installed. But hey, when did looking silly ever stop a hacker from making something awesome? :)

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".
