What Are Your Most Popular Dev Kits or Reference Design Kits?

rscasny

I was asked this question the other day. What Are Your Most Popular Dev Kits or Reference Design Kits? On impulse, I would venture to say the Raspberry Pi, Beaglebone. I'm sure there are others. Sensor kits, FPGA kits, Motor Contr0ol kits, Power kits, come to mind, but I'm not sure which ones element14 would consider "popular."

So, I figured I would ask you.  What are your most popular kits?  If you have the time, please leave a comment below. 

Thanks

  • I'll answer a different question: which dev kits are the least popular for me.

    I am not a fan of a development kit with many headers with nothing to connect to. For example, there might be a connector for an "external display" or "camera," but no products on the market fit those connections. (Or maybe there used to be, but now they are no longer offered.) It is nice if the vendor provides those accessories, but it is also annoying when there is only one option--why not just include it in the kit then?

    Related, it is also very frustrating when a dev board has "custom" connectors to access some of its signals. I put custom in quotes because, technically, they are available, but they are not a part that is normally stocked at distributors. So even making your own board to plug into it becomes an instant hassle and relatively expensive.

    Out of fairness, I'll not mention the vendor who has done this on several of their recent products.

    Sometimes, it seems like the product manager (or the engineers) do not take a step back and think about how a user NEW to their platform can make use of it.

    Grove modules are popular, but very few places seem to stock the connectors and mates. Does Newark stock them? Has anyone seen a datasheet? What is the actual manufacturer's part numbers?

    Hi Doug,

    I received some cables when I picked up a Grove board for an Arduino a few years back.

    I can't say I have seen the connectors/mates, but then I have not searched.

    Farnell have stocked the PCB headers for a while now

    SEEED STUDIO Grove, Connector, 4 Pin 2mm, 10 Pack - 110990030

    I posted a link to the datasheet a while back. Now if only I could find it...

    Adafruit claim that their 4pin JST-PH 2.0mm are compatible with Grove

    "...The 4 pin size is even compatible with Grove!..."

    ( Can you tell that someone here has been down this long and winding road before ? )

    With a soldering iron and some patience, any connector pair will mate at least once.

    I've tried JST - the pitch is the same, but from what I remember offsets and grooves in the shell are different.

    Just had a quick look here and perhaps 'compatible' after attacking with a Dremel...

    Limor even says it in the video, so not like it was a typo that was copy and pasted all over the website:
