The Nordic Semiconductor NRF52833-QIAA-R is a 2.4G Hz RF transceiver supporting data rates up to 2Mbps. Alongside the radio it provides an extensive peripheral set with 42 GPIO, 8 ADC channels, and 2-Wire, I2C, I2S, SPI, UART and USB interfaces, allowing it to act as the single wireless and control device on a board. The NRF52833-QIAA-R operates from a wide 1.7V to 5.5V supply, so it can run directly from a battery or a regulated rail without additional conversion. It is supplied in a 73-pin QFN with an 850um height, rated for -40 to 85 degrees C ambient with a 110 degrees C maximum junction temperature.

Devices in this class combine a 2.4G Hz radio with enough I/O and peripherals to run the whole application, so the NRF52833-QIAA-R is typically the only active device on a small wireless board rather than a companion radio. Common applications are short-range connected products: sensors and asset tags, wearables and health monitors, wireless human-interface devices, smart-home and building-automation nodes, industrial monitoring endpoints and USB-attached wireless dongles. The 1.7V to 5.5V range covers both coin-cell and USB-powered designs, and 42 GPIO allows direct attachment of displays, buttons and sensor arrays without an expander. Buyers are IoT product developers, wearable and medical device manufacturers, and industrial monitoring OEMs; note that this catalog record specifies an 85 degrees C maximum operating temperature while the product title cites 105 degrees C.
