This is the king or the Raspberry Pi boards.
An excellent board with an amazing reputation for only $35.
If you want to integrate a Raspberry Pi into an industrial setting then the Compute Module might be a better choice.
This is essentially a $40 cut-down version of the Raspberry Pi, featuring:
Turn your Raspberry Pi into a mini laptop with this $275 display and case that's compatible with any Raspberry Pi board.
This is a must for robotics!
The Adafruit 16-Channel 12-bit PWM/Servo HAT will drive up to 16 servos or PWM outputs over I2C with only 2 pins. The on-board PWM controller will drive all 16 channels simultaneously with no additional Raspberry Pi processing overhead. What's more, you can stack up to 62 of them to control up to 992 servos - all with the same 2 pins!
All that for $17.50.
Works with any servo that can be powered by 5V and take 3.3V logic level signals.
If you want you Raspberry Pi to take to the skies, then you need the Navio2 Linux autopilot board.
This $170 board features a built-in GPS and barometer, and well as dual inertial measurement unit and ports for Wi-Fi or LTE antennas that allow you to control your drone project even over the internet.
This is an updated 320 x 240 2.8-inch TFT resistive touchscreen specifically designed to fit the Pi Zero, Pi 3, Pi 2 or Model A+, B+ boards.
At $35 this is a great way to jazz up a project.
This is a 320 x 240 2.8-inch TFT touchscreen display suitable for Raspberry Pi projects. The display is designed for the form factor of the Pi 1 Model A or B but it will work with the Pi Zero, Pi 3, Pi 2 or Pi 1 Model A+ or B+, or any Pi with a 2x20 connector.
For only $35, this is a great addition to any project.
Turn a Raspberry Pi Compute Module into a media stick for your TV's HDMI port for only $24.
A collaboration between Microsoft's IoT division and Adafruit, this pack's the best way to get started using both Windows 10 on your Pi and to start doing some popular projects with the internet of things.
For $75 you get:
But that's not all! You also get the following components:
Here is a $20 sensor board for your Raspberry Pi that allows you to you measure temperature, pressure, light level, color, 3-axis motion, compass heading, and analog inputs.
The Pimoroni Picade Cabinet is a stylish, retro, and fun arcade cabinet for your Raspberry Pi!
The Picade Cabinet comes in kit form for you to build at home. All parts, panels, and components are included - you just need to supply the Raspberry Pi and power adapter.
But at $240, retro gaming doesn't come cheap, and you've still got to add the price of a Raspberry Pi to that.
A $9 Wi-Fi dongle compatible with Raspberry Pi as well as PC and Mac.
Break free of the limitations of storing data on an SD Card by adding a low-power-consumption hard drive to your project in the form of a WD PiDrive.
250GB of storage starts at $29.
Why be tied down with a wired keyboard when for $25 you can pick up a wireless keyboard complete with touchpad.
Give your Pi project some eyes (well, one eye at least) with this $30 camera module.
GameGRRL is a portable Raspberry Pi running MAME, NES, Atari2600 and other fine emulators (via RetroPie/EmulationStation).
The $47.50 kit comes with
To this you need to add:
VoCore2 is an updated version of the highly-popular coin-sized Linux computer VoCore. Like it's predecessor, VoCore2 is totally open-source, and costs $15. This is a small, low-cost, totally open-source (both the hardware and software) computer that's ideal for projects such as IoT or building your own custom router.
VoCore2 also features an optional camera and dock.
If that's not enough there's a stripped down version of the VoCore2 that's available for a mere $4!
At $9, C.H.I.P. is a perfect demonstration of how cheap computing has become. You get what would only a few years ago have been desktop power on a tiny board.
The easiest way to create internet-connected devices - no programming, soldering or wiring required. IFTTT support allows it to connect with any web service, like Facebook, Gmail and Twitter, or hardware like NEST and Philips HUE.
All for just $59.95.
The PixelPro features a i.MX6Q Quad-core ARM Cortex-A9 running at 1.0 GHz, with 2D and 3D GPUs and an embedded 2GB 64-bit DDR3 RAM, which means that it is capable of running rich multimedia applications, embedded web servers, digital entertainment systems, industrial control systems, and high definition video.
At $129.95, the PixelPro is not cheap, but you get a lt of power for the cash.
At around $92, the Intel name doesn't come cheap, but this Arduino-compatible board is turning out to be a popular choice.
The NanoPC-T3 is the bigger brother of the NanoPi 2 Fire, and features an octa-core processor which has enough power for commercial and industrial applications.
BeagleBone Black is a low-cost, community-supported development platform for developers and hobbyists. This $55 board allows you to boot Linux in under 10 seconds and get started on development in less than 5 minutes.
A $135 quad-core board that's just as at home running Android as it is Linux.
A $40 Arduino that's idea for integration into a commercial or industrial product.
The Parallella computer is a high performance, credit card sized computer based on the Epiphany multi-core chips from Adapteva. Starting at $99, the Parallella can be used as a standalone computer, an embedded device or as a component in a scaled out parallel server cluster.
A cheap, $23 quad-core powered board that's ideally suited for hobbyists.
Banana Pi M3 is a super charged single board computer with an Octa-core processor and 2GB of RAM. It also features Gigabit Ethernet, 2 USB, SATA, WiFi, Bluetooth, and HDMI connection. It can run on a variety of operating systems including Android, Lubuntu, Ubuntu, Debian, and Raspbian.
