The graphics processor onboard this power-packed 2.32GHz quadcore development board, with 2GB of RAM and 16GB of eMMC flash storage, is great for computer vision tasks on autonomous robotics. The NVIDIA Jetson TK1 powerful GPU, with an astonishing 192 CUDA cores (Compute Unified Device Architecture), allows non-graphics software tasks to... Read more »


WiPy is an excellent device for those who know Python (or want to learn) and it’s designed to easily connect to home networks. The board doesn’t draw much power while crunching numbers — only about 14mA — and can drop into a super low-power hibernation state drawing just 5µA. With... Read more »


Already supported by a strong community, The Raspberry Pi Foundation sold out of the initial batch of $5 Pi Zeros — all 20,000 of them — within the first 24 hours of its launch. Zero is a stripped-down version of the Raspberry Pi B+, but don’t let that fool you. This is one powerful... Read more »


The team at krtkl (pronounced “critical”) is crowdfunding Snickerdoodle, a $55 hybrid development board that has an ARM application processor with an onboard FPGA. It is programmable from a cellphone, has 230 general purpose input/output pins (GPIO) including ground pins, and might just be the next big thing for Makers in... Read more »


With its onboard cellular antenna, this diminutive board will offer a huge range of deployment options and alleviate the hassle of using a custom cellular breakout board with your micro controller projects. They’re offering two versions, with either 2G or 3G connectivity. It thankfully also reduces the frustration of dealing with mobile... Read more »


The Particle Photon is designed for the Internet of Things, and Particle runs its own cloud infrastructure to support its ecosystem of devices. Configuring the Photon to connect to the cloud is a breeze. Download the Particle smartphone app (Android or iPhone), connect the board to your network, and start coding using Particle’s web-based development environment. Those familiar with Arduino will find that...

Using the Pi is just like operating a computer. Connect peripherals (keyboard, mouse, and monitor), power on the device, and you’re basically running a desktop computer from the ’90s. The Raspberry Pi 2 runs Raspbian Linux, which offers a graphical interface and since Linux has hundreds of development environments for programming languages — ranging from assembly and C/C++,...
