When it comes to single board computers, the Raspberry Pi is the undisputed heavyweight champion of the world. Sure, it's not the most powerful, or the most compact, or even the cheapest. But its devotees are legion.
The current version is the Raspberry Pi Model 3 B+, released for "International Pi Day" on 14 March 2018. Topline specs are 1.4GHz 64-bit quad-core processor, dual-band wireless LAN, Bluetooth 4.2/BLE, faster Ethernet, and Power-over-Ethernet support (with separate PoE HAT).
Sounds like a tidy package, right? Retailing for $35, it's perfect for a variety of DIY projects, whether it's connecting your 3D printer to a network, or learning to code, or putting together a streaming media hub.
Well, the truth of the matter is, where Raspberry Pi blazed a trail for single board computers, a multitude of imitators have followed in its wake. And there's a sizeable group of people who do need something more powerful, or more compact, or even cheaper.
Without further ado, here's a selection of the best Raspberry Pi alternatives you can buy in 2018. It's a fast moving market, where a byte-sized contender will appear and disappear in the fritz of a neuron. And you're taking a risk with available software or community support, which cannot hope to rival the RPi.
But if you're feeling brave, these are the single board computers worthy of consideration.
