What Can You Make with These Development Boards?

Raspberry Pi 2 (left), Gizmo 2 (center), and Creator CI20 (right) are just some of the new development boards available.

I remember when building a computer from scratch was a major undertaking. Hobbyists and developers used to plug together S100 boards to make a system that is less functional than a microcontroller that fits inside a 2 mm by 2 mm chip. The PC revolution was built around motherboards that eventually usurped the collection of peripheral boards that normally included a disk controller, display controller, and network adapter or modem.

These days the entire system fits on a small, single-board system like the  Raspberry Pi 2, Gizmo 2, and Creator CI20 (see the figure). They sport USB, 1080p HDMI video, and 1 Gbyte of DRAM.

What can you build with these compact wonders? Just about anything from 3D printer controllers to robots. They even make great multimedia platforms running Kodi (formally XBMC).

Raspberry Pi 2

The $35 Raspberry Pi 2 updates the popular Raspberry Pi by moving to a quad-core, 900 MHz Broadcom BCM2836 system-on-chip (SoC). It has a 10/100 Ethernet port (see “Raspberry Pi 2 Goes Quad Core”). The four USB ports are very handy when turning the system into a compact PC and the microSD slot lets you pack in gigabytes of flash. The 40-pin header provides access to a plethora of expansion boards that have grown up around the Raspberry Pi series.

Gizmo 2

The $199 Gizmosphere Gizmo 2 has a dual-core, AMD GX0210HA APU (see “APU Blends Quad Core x86 with 384 Core GPU”). The Radeon HD 8210-class GPU delivers 85 MFLOPS while using under 9 W of power. It has a miniPCIe/mSATA port underneath, along with a microSD slot. It is a high-performance system with Gigabit Ethernet socket and PCI Express expansion interfaces. It even has a USB 3.0 port. Most compact platforms still deliver USB 2.0. This board exposes additional interfaces using edge connectors. It comes preloaded with TimeSys Linux.

Creator CI20

The $65 Creator CI20 uses Ingenic’s dual-core, 1.2 GHz JZ4780 that is based on Imagination’s MIPS32 processor with a PowerVR SGX 540 GPU. The GPU is similar to what is found in an iPhone 4. Digilent's chipKIT Max32 uses Microchip’s PIC32 that is also based on the MIPS32 architecture (see “Arduino, Raspberry Pi or BeagleBone?”).

The CI20 has 10/100 Ethernet, but it also has Bluetooth and 802.11b/g/n support. The other two need additional boards for wireless support. It actually makes a very nice wireless bridge for Internet of Things-type applications.

These days Linux typically is the operating system of choice with Linux-based Android a close second. Platforms like the Gizmo 2 can run Microsoft Windows and other x86 operating systems out of the box.

While all three are similar in size, they are quite different in features and target applications. They get mixed in with platforms like Arduino, BeagleBone, and Edison. They are all readily available from a range of suppliers like Avnet, DigiKey, Element14, Mouser, and Sparkfun.
