Meet Snickerdoodle, an Affordable, Powerfully Maker-Focused Raspberry Pi Rival

A field-programmable gate array means Krtkl's Snickerdoodle can tackle complex projects, like robots or drones, unlike the locked-down Raspberry Pi.

The $35 Raspberry Pi mini-PC serves as a cheap, yet damn fine introduction to both computer programming and the joys of what’s become known as “making”—using cheap, sensor-laden computer boards to power devices that interact with the world. Makers can create some amazing projects with the Pi, but the limited number of general-purpose input/output (GPIO) pins on it hinders the creation of truly complex projects.
Enter krktl’s more maker-friendly Snickerdoodle, a $55 board that aims to become the Raspberry Pi for robots by bringing flexible, pro-level hardware to the masses via a crowdfunding campaign.
