  • The $35 Raspberry Pi has blown past all expectations, selling more than 14 million boards.

    While the Pi wasn't the first single-board computer, its success has helped spawn many similar devices.

    Some of these credit card-sized computers are starting to surpass the specs of the Pi 3, cramming in more memory, faster processors and additional features such as Gigabit Ethernet or support for 4K displays.

    These extras come at a price, with most of these challengers costing more than the Pi 3, while also not sharing the Pi's extensive range of software, projects and community support.

    But if you're looking for a more muscular alternative to the Pi, this is what's on offer, from the cheapest, through to premium single-board computers for those who prize power over price.

The $35 Raspberry Pi has blown past all expectations, selling more than 14 million boards.

While the Pi wasn't the first single-board computer, its success has helped spawn many similar devices.

Some of these credit card-sized computers are starting to surpass the specs of the Pi 3, cramming in more memory, faster processors and additional features such as Gigabit Ethernet or support for 4K displays.

These extras come at a price, with most of these challengers costing more than the Pi 3, while also not sharing the Pi's extensive range of software, projects and community support.

But if you're looking for a more muscular alternative to the Pi, this is what's on offer, from the cheapest, through to premium single-board computers for those who prize power over price.
