Nordic Semiconductor’s Bjørn Kvaale shows the latest cellular IoT NB-IoT, LTE-M, GPS and BLE Bluetooth 5.1 Direction Finding, Zigbee and Thread solutions for development on the market today. Showing their Bluetooth Low Energy solutions including the newly launched nRF5340 SoC featuring dual Arm Cortex-M33 processors, truly secure, with two flexible processors, the advanced feature set, and an operating temperature up to 105 °C, makes it the ideal choice for professional lighting, advanced wearables, and other complex IoT applications The nRF5340 PDK is the preview development kit for the nRF5340 SoC, containing everything needed to get started with development, on a single board. The PDK supports development with an extensive range of wireless protocols. It supports Bluetooth Low Energy, including the Long Range and high-speed 2 Mbps features. Mesh protocols like Bluetooth mesh, Thread and Zigbee can be run concurrently with Bluetooth LE, enabling smart phones to provision, commission, configure and control mesh nodes. NFC, ANT, 802.15.4 and 2.4 GHz proprietary protocols are also supported. The PDK is bundled with an NFC antenna that quickly enables testing of nRF5340’s NFC-A tag peripheral. A SEGGER J-Link debugger is on the board, enabling full-blown programming and debugging, of both the nRF5340 SoC and external targets. All analog and digital interfaces, and GPIOs are available via headers and edge connectors. The kit is Arduino Uno Rev3 hardware compatible, meaning it can be easily interfaced with external device shields, including the Power Profiler Kit. Four buttons and four LEDs simplify input and output to and from the nRF5340 SoC, they are all user-programmable. An on-board external memory is connected to the 96 MHz QSPI peripheral in the nRF5340 SoC. The PDK is typically powered with USB, but can be powered by a wide range of sources, within the supply range of 1.7 to 5.0 V. In addition to USB, it can be powered with external source, but also includes a CR2032 battery holder and a Li-Po battery connector, for in-field testing. Current consumption can be measured by using the dedicated current measurement pins. The nRF Connect SDK is the software development kit for the nRF5340 SoC, and it has board support for the nRF5340 PDK.
