In a column earlier this year I introduced. At the time I placed various restrictions on the kits that would be considered, for example, only those that were equipped with wireless technology, whose vendors had partnerships in place with various cloud providers, and so on. I was also reticent to include kits I viewed as more exclusive to the hobbyist market, such as the Raspberry Pi, BeagleBoard/Bone, and the ubiquitous Arduino. However, after seeing kits that fall outside of these parameters repeatedly used by professionals for prototyping – and at times in commercial deployments –
I opted to remove the cloud requirement, as cloud services offerings are not bundled with most kits, and even if they are it’s not a requirement to use them or for unimpeded operation of the kit (also, a cloud selector sounds like a good tool of its own). Also, on-board wireless is no longer mandatory since a great many useful, low-cost development kits employ a modular, add-on approach to connectivity through clicks and capes. Next, given the widespread(and, frankly, because some of them are just all-around better systems than those from vendors), I’ve decided to include the Arduinos and BeagleBones of the world as well. Finally, I’ve added in a parameter simply called “Chip” that calls out the exact microcontroller or microprocessor the kit is built around.
But the biggest change to you, the user, is in the functionality of the platform as it stands today. Upon visiting, you’ll notice a massive upgrade from the static image I originally provided to a dynamic, sortable table. In addition to a normal search function in the upper right, you are able to show and hide the navigation buttons to arrange the listing by:
- Manufacturer – In case of allegiances to a particular vendor.
- Chip – For easy identification of the processing element, which along with software and tools, is likely what you’re evaluating.
- Compute – To identify the core at the heart of the processor for instances where application requirements may dictate a particular core size, frequency, etc.
- Memory – Usually on-chip, in which case I have used parentheses to indicate as much. In cases where there is additional memory available on the board, I will identify the part.
- I/O & Peripherals – Any signal, connector, or input of relevance to a designer is included here.
- Wireless – Currently I’m still only including on-board wireless in this section, so you’ll want to be sure to use the sort function on the right side of the column heading.
- Software & Tools – Any software that is recommended for use with the board is shown here, which is often freely available (at least in limited versions).
- Notes – A brief description of mine to give you a quick sense of the kit’s intended uses.
- Cost/Buy Now – The price and a link to purchase kits of your choosing are listed in this field.
- New Kits – This indicates a recently added kit.
Some additional information on the last two bullets will hopefully provide some clarity on the tool’s inherent structure, and how we will be maintaining it going forward is in order.
First, this rendition of the Development Kit Selector is the result of a partnership between Embedded Computing Design and, and the Cost/Buy Now field is intended to allow interested parties to be taken directly to the distribution source of a kit rather than returning to Google to search for how to obtain one. In addition, this gives me (and you) access to a large repository of commercial kits, rather than being forced to troll the Internet every time a kit is released.
Second, as you can imagine, this tool requires a large amount of datasheet diving on my part. Digi-Key has provided hundreds of kits for inclusion in the Selector, but, as you will see (or perhaps already have seen) we are currently displaying 25. Not to worry, though, as I will be updating the tool on a weekly basis with 5-10 new kits, which will be chronologically sortable using the “New Kits” field. If you subscribe to the, therein you will be provided with an highlights of a few of the freshly uploaded kits from the past week. If you don’t receive IoT Design, you can
Lastly, remember that this tool is designed for you, to help you with your design process. If you have any questions, suggestions, or comments on the format of the Selector, updates on kits or tools, or are curious about one kit or another, please leave a comment at the bottom of the page. I will be routinely monitoring this, and welcome your feedback.
