14 Raspberry Pi Zero Alternatives That Cost Less Than $20

The Raspberry Pi Zero and the Raspberry Pi Zero W were added to the line-up of Raspberry Pi’s a while back. These ultra-small form-factor SBC’s have been a big hit and continue to be a part of Raspberry Pi projects from the maker and DIY communities.

Due to the smaller form factor and the prices these boards are targeting, they have had to cut down on many features like a dedicated Ethernet port, slower processor (compared to their full-fledged cousins).

However, you can still build some really cool projects with tiny Raspberry Pi Zero W like devices.

In an earlier article, we listed the best alternatives to Raspberry Pi. In this one, I’ll list some alternatives to Raspberry Pi Zero and Zero W. These should be the perfect tiny single board computers for IoT and embedded systems.

Why Do We Need Raspberry Pi Zero Alternatives?

Even though the Raspberry Pi Zero was released at $5 and the Zero W at $10, it’s often very challenging to find them at those prices even in the US. Outside the US, they usually cost around $12 – $20.

Whether Raspberry Pi releases a successor to it when you read it (or discontinues the Zero), you will always find the replacements handy.

Sure, Raspberry Pi boards are considered as the de-facto standard. But, you might find the alternatives offering something better for your use-case.

While most of the board run a type of embedded Linux distro, you should be able to try other operating systems tailored for

Let's get started!
