Raspberry Pi Alternatives [2021] – 8 Best Single Board Computers

The rise and rise of the Raspberry Pi’s popularity – as a home server, media box, emulation machine, or maker platform – has led to a host of imitators, and in some cases, successors.

Finding the right single-board computer for your project will make development easier- so here’s a summary of some of the single-board computers getting about in 2021.

8 Best Alternatives to the Raspberry Pi

We’ll only include boards with built-in memory and video out – all in one single board computers and limit to boards with GPIO for sensors and controlling motors and building things – true Pi replacements.

Need a single-board computer and want something other than a Pi? Below are the best 8 alternatives to the Raspberry Pi:

Banana Pi M4


The Banana Pi M4 is an affordable rival for the Raspberry Pi 4. It has a similar form factor to the Pi 4 but with a full-sized HDMI port and a lower price – which some would consider an advantage over the latest Raspberry Pi, though it does have weaker video playback.

LattePanda SBC Specs


There are various variants and sub-variants of these boards from the same manufacturers with slightly varying specs – you’ll need to consider the cost of the alternatives, and of course, how much power you’ll need. A home media server will need some processing grunt, but if you’re just flashing LEDs or monitoring the weather, a lower power board might be in order (and cheaper!).

If you’re working on a hardware project, you may want to consider using an Arduino as the brains instead – check out our Arduino / Raspberry Pi comparison for more info!
