BLE Carbon 96Boards IoT Edition Board Runs Zephyr OS

September 27th, 2016 Leave a comment Go to comments

Linaro Connect Las Vegas 2016 is taking place right now, and the organization has some very interesting development, with a new focus on the Internet of Things thanks to the creation of LITE (Linaro IoT and Embedded) segment group that will work on “delivering end to end open source reference software for more secure connected products, ranging from sensors and connected controllers to smart devices and gateways, for the industrial and consumer markets”. The first LITE IoT Reference Platform release to be made in December 2016, but in the meantime, Linaro introduced 96Board IoT specifications, as well as the first compliant board with the launch of Carbon board (aka BLE Carbon) running Zephyr OS.

You’ll find the software and hardware documentation on 96Boards Carbon page, as well as Seeed Studio Wiki, since they are the designer and manufacturer of the board.

As with other 96Boards specifications, 96Board IoT Edition (IE) specification defines requirement for multiple revision of boards either using Cortex-A or Cortex-R/M profile, and IE standard (60x30x9mm) or IE Extended (85x54x12mm) form factor. On top of that you’ll also have board with 3.3V I/Os, and others with 1.8V I/Os. That means that BLE Carbon board is compliant with “96Board IoT Edition standard using Cortex-R/M profile and 3.3V I/Os“.

The specifications also mandates at least one wireless interface such as Zigbee and Bluetooth LE, as well as optional Ethernet, USB, and micro SD card support.

Seeed Studio is now taking pre-orders for the BLE Carbon board for $27.95 with shipping planned for October 20th.

    STM32F401 + nRF51822? Feels like I’ve gone back in time to 2014.

    That looks a lot more sensible

    Nice find! It’s not listed on 96Boards website yet however, so I’d suspect software support might be a little behind for now, despite both board shipping at the same time. I’ll ask Seeed Studio…

    Actually Zephyr OS already supports the BLE Nitrogen board! So in terms of software it may even be better than the one you posted.

    That’s great. My Seeed Studio’s contact does not know why it’s not listed on 96Boards website.
