The Nordic nRF52840-QIAA-R is a multiprotocol 2.4 GHz SoC with an Arm Cortex-M4 core and FPU running at 64 MHz, 1 MB of Flash and 256 KB of RAM. Its radio supports Bluetooth 5 LE, including long range, IEEE 802.15.4 for Thread and Zigbee, and 2.4 GHz proprietary protocols.
It also integrates USB 2.0 full-speed, QSPI, SPI, I2C, UART and PWM, which lets one chip handle both the application and the wireless link. The part comes in a 7x7 mm aQFN-73 package on tape and reel. It is a common choice for wearables, Matter and Thread devices, USB dongles and sensors. Nordic supports it with the nRF Connect SDK.
