Ever since Arduino came into being, development boards have become a very common tool among engineers trying to design various kinds of circuits. The market is flooded with development boards with all sorts of features. Any requirement you might have, there is a development board for it. You want to prototype for the Internet of Things (IoT), you have a whole set; you want industrial grade, there is a different line; so on and so forth.

Aided by the open source movement, these boards provide a backbone for electronics designers. Most of these solutions consist of connections that are pre-made and require simply adding the finishing touches. Priced as low as a ₹ 200, these boards can get you started on the way to becoming a circuit designer.

Increased availability of development boards

The availability of inexpensive development boards and the possibility of creating projects have been blessings for designers. Prakash Mohapatra, product manager, Toradex, says, “The extensive ecosystem of both hardware and software, backed by strong community support and low upfront cost, make these an ideal choice for hobbyists and academicians.”

These boards are now being used for prototyping circuits before these go into production. For hobbyists, these have come in handy. Automated plant watering systems or automated garage openers have become mainstream projects, thanks to the development boards. Plugging a cable and simply controlling the boards from a computer makes it sound so easy.

Tough competition for development.

Be it a simple garage door opener or a fire breathing robot, Arduino is what comes to mind as the design solution. Initially aimed at hobbyists, the range of Arduino boards has now become a means to test and prototype projects before going into production. It is an attractive solution for professional engineers as a low-cost method for validating a project’s design and quickly building a prototype. The availability combined with a wide variety of possible applications make it a very interesting solution for hobbyists and industrialists alike. But it is not just Arduino that is making a name for itself.

Most companies that have launched microcontrollers in the past decade have seen development support as vital—continuing a trend to support low-volume users. In some cases, microcontroller and software vendors have Arduino as a target for their own product development.

Of late, many new boards have entered the market. For engineers looking to try development, Tivaware from Texas Instruments is a lucrative option. It is compatible with Code Composer and Energia that give a hands-on experience for academicians looking to enter development professionally.

Curiosity boards from Microchip are also an interesting addition. Based on PIC32 microcontroller, these allow for the IoT and connectivity application development.

Mbed initiative from ARM is another option for programmers. It provides an ecosystem for the development of IoT devices, so that part-time developers can join the race.

And, if things were not diversified enough, developers have successfully added JavaScript and .Net platforms to the mainstream environment of C and C++ for usage in development boards to allow software aficionados to enter the game.

Ever since the launch of Raspberry Pi, the definition of computing has changed radically. Tinkerers have started using Raspberry Pi to make robots, data accumulators, phones and desktop computers. Applications are only limited by one’s imagination.

BeagleBoard is another popular board for engineers who like working on Linux. The top-of-the-line board consists of 2GB DDR3 RAM and 4GB 8-bit e-MMC onboard flash memory. With 3xUSB 3.0, eSATA, HDMI and 2xEthernet, it is a serious contender for top performance in development boards.

This board finds a strong contender in UDOO X86 Ultra, which sports a quad-core Intel N3710 SoC clocked at 2.56GHz. Icing on the cake is Intel HD 405 graphics on board, which are supported by 8GB DDR3 RAM. Come to think of it, my PC has got poorer configuration, much poorer!

An increasing number of interface options

A lot of development boards come with a multitude of interface options ranging from the very popular USB to technical ports like RS232. T. Anand, technical architect, Knewron, says, “Interfaces like MOD-BUS, RS232 or peripheral component interconnect (PCI) slots still exist and could be prominently seen on industrial boards, while general-purpose boards usually have USB interfaces.”

Arduino, for example, offers Registered Jack 45 (RJ45) and USB 2.0, among others, for connecting and loading programs from a computer. Most ARM based devices include a Joint Test Action Group (JTAG) interface. This can be used to program on-chip or external flash, or load directly into RAM. The JTAG is also the interface for on-chip debug and trace features. Wireless is also being used as one of the interfaces.

  1. Very good article, but Arduino is used for a few reasons, and there are some that are more powerful than the common Uno R3. One is that you can buy and arduino clone for a few bucks. You can also develop on the arduino, then make your own board and just use the CPU you tested in the Uno. Raspberry Pi’s are used for so many projects because they are so capable. So if making a computer system is one your mind, a Raspberry Pi might work, but on a novelty level. The better things that are done with Raspberry Pi’s are DVR’s, and KODI. A Raspberry pi can be configured as so many other things, but most just use the code from someone else, where Arduino is mostly programmed by the person using it.
    One of the projects i put together is a CW keyer, a project that has been going on for a long time. There are a number of them, but there is one particular keyer that is very nice.
    Anyone who ventures out to one of the more powerful boards, is usually doing it for more reasons than just for the power. They might be doing it for a college project, or because they are well versed in the programming needed to make the board useful. “Need” is what drives people to much more powerful boards. You can chain 3 cheap arduino CPU’s together with a master and two slaves, and do a lot with it. They are cheap, and easy to work with.
