A compact design helps use in the application where space is a constraint so it can also be used in product as a whole if the interfaces provided are sufficient for the application.

Piunora CM4 carrier board makes it a useful SBC along with Raspberry Pi CM4. Software-wise it is fully compatible with all the software and frameworks which works on Raspberry Pi CM4 module considering the available hardware interfaces on the board.

Features & Specifications

Piunora Pro Vs Piunora Lite

There are two version available for the Piunora, Lite and Pro. Both board have the same PCB but Lite version doesn’t have two connectors soldered on the bottom side for obvious space and cost savings purpose. Piunora Lite doesn’t have the following:

Let’s see how they progress.

Where to buy Piunora CM4 Carrier board?

Piunora CM4 carrier Board was launched on Crowd Supply a couple of months back and now fully funded. Backers will be getting their boards soon.

Piunora Lite costs just 30$ where as Piunora costs slightly higher that is 39$.

Please note you need to buy Raspberry Pi CM4 Module separately, also there are no cables, etc. which comes along with the board.

You can buy one from Crowd Supply now.

I am also building one fully Open Source Custom Carrier board for Raspberry Pi CM4, if you are interested, do leave a comments below and I will share the details. I will be using Altium Designer.

I hope you found this post interesting.
