The company has also launched nRF52840 Preview Development Kit to get started with evaluation and development.  The development board is hardware compatible with Arduino Uno Rev. 3 to allow the use of common Arduino shields, and also includes 4 LEDs and 4 buttons, all programmable by the user. It supports Bluetooth 5, Bluetooth low energy, ANT, 802.15.4 and 2.4GHz proprietary using the latest S140 SoftDevice software stack, as well as NFC thanks to an external antenna included in the kit.  The kit is compatible with Nordic Software Development Toolchain using Keil, IAR and GCC, and can be programmed & debugging with Segger J-Link OB.

Samples and the development kit are available now at an undisclosed price. You’ll find more details about the nRF52840 Bluetooth 5 SoC and development kit on the product page.

    Interesting, a couple of years ago Nordic wasn’t the least bit interested in ZigBee and now this…
    I guess they’ve seen where the competition is head and decided that they wanted to stay competitive.
    Let’s hope the pricing is competitive too, as this looks like a really nice solution.

    To be honest this probably has very little to do with Zigbee itself and more to do with supporting Nest’s Thread – Nordic clearly sees the smart home as a huge market and already has one of the best HomeKit implementations.

    With the faster and more interoperable Bluetooth Mesh protocol coming next year it’s also a good “bridge” chip much like they do with BLE+ANT already.
