Well, first off I visited the Arduino page. I found a few new things. First off, they use the name Arduino in the US, while Genuino is used outside the US.
They have a great summary chart on their products page that shows what is what in terms of entry level, enhanced, etc.
And there are a few new boards.
First up is the Arduino 101, which makes use of Intel's new Curie SoC that I had noted in my IoT presentation last year at HackMiami. This may be the only available use of it so far. This small button-sized SoC sounds real interesting, and you can make use of it in this $30 board.
Next up is the Arduino MKR1000, which is a small board/module that combines the power of the 32bit Zero with a WiFi shield in a small form. Sounds interesting.
Raspberry PiSeveral new things in the realm of RPi. I think most have heard of these by now.
Raspberry Pi Zero
The Zero is a $5 version of the RPi. They pulled this off by stripping off components. You get an HDMI connector and 2 USB ports. You have to add in a 40 pin connector strip. While it may be foolish to try to use the Zero as a replacement for the 2 or 3, the cost may allow people to use the more powerful Zero in unique situations.
Raspberry Pi 3- Model B
Going the other direction is the new RPi 3, which is only available in the large "Model B" version. This one takes the RPi 2-B further, while staying at the same cost as the 2-B. A more powerful processor, plus built in WiFi and Bluetooth.
Raspberry Pi Touchscreen
An additional RPi product from the Foundation is a 7in touchscreen. This connects to the DSI connector on the boards, so you don't have to use up other connectors.
BeagleBoneWell, there is a new version of the BeagleBone Black: the SeeedStudio Beaglebone Green. Built by SeeedStudio with BeagleBoard, it takes the basic BBB design and adds in 2 Grove connectors. Sounds like an interesting extension.
Well, that's it. I don't see anything else new out there . If you know of others, post them in the comments.
