Nordic Semiconductor - nRF52840 & nRF52840 Preview Development Kit

nRF52840

nRF52840 is an ultra-low power 2.4 GHz wireless system on chip (SoC) integrating a multiprotocol 2.4 GHz transceiver, an ARM® Cortex®-M4F CPU and flash program memory. It is the ultimate SoC for any short range wireless personal area network or IPv6-enabled automation application.

nRF52840 supports Bluetooth® low energy, the ANT™, 802.15.4, and user-proprietary 2.4 GHz protocols. Fully qualified Bluetooth 5 and ANT stacks are available for the SoC. An 802.15.4 protocol library and a certified USB stack are also available.

The nRF52840 SoC is part of the nRF52 Series that offers code-compatible devices across the series and simple software migration from the nRF51 Series.

nRF52840 Preview Development Kit

The nRF52840 Preview DK is a versatile single board development kit for Bluetooth® low energy (including Bluetooth 5), ANT, 802.15.4 and 2.4GHz proprietary applications using the nRF52840 SoC. The kit supports all development for the nRF52840 SoC.

The kit is hardware compatible with the Arduino Uno Revision 3 standard, making it possible to use 3rd-party shields that are compatible to this standard. An NFC antenna can be connected the kit to enable NFC tag functionality. The kit allows access to all I/O and interfaces via connectors and has 4 LEDs and 4 buttons which are user-programmable.

The kit supports the standard Nordic Software Development Tool-chain using Keil, IAR and GCC. Program/Debug options on the kits are Segger J-Link OB.

All necessary firmware and Host software is provided to implement a full design at both ends of the application. The firmware runs on the nRF52 Series SoCs. Host software supports Linux.
