nRFnRF52840-QIAA-R
Overview
The nRF52840-QIAA-R is a 2.4 GHz RF System-on-Chip that supports Bluetooth 5 and IEEE 802.15.4 wireless protocols. It combines a radio and microcontroller-class logic in a single package for battery-powered wireless endpoints. The device is targeted at low-power IoT, mesh networking, and wearable applications.
Why Choose This Part
This SoC integrates a 2.4 GHz radio and application processor in one package, reducing BOM cost and board area compared with separate MCU and transceiver solutions. Nordic provides extensive software support (SDKs and reference stacks) and a strong community, which accelerates development. The part is optimized for low-power wireless endpoints and mesh networking use cases, making it a common choice for battery-powered IoT products.
Applications
Getting Started
Start with the nRF52840 DK (development kit) or the nRF52840 USB dongle to evaluate hardware and radio features. Use Nordic's nRF Connect SDK or the nRF5 SDK, Segger Embedded Studio or GCC toolchains for firmware development, and nRF Connect for Desktop for flashing and logging. Consult Nordic documentation and example projects for Bluetooth, Thread, and Zigbee reference implementations.
