NRF52833 RF Transceiver Bluetooth 2.4GHz 73-VFQ: Datasheet, Pinout, and nRf52833 vs nRF52840

The nRF52833 is a low-power multiprotocol SoC with a Bluetooth 5.1 Direction Finding radio that can operate in a wide temperature range of -40°C to 105°C. It supports Bluetooth 5.1, Bluetooth mesh, 802.15.4, Thread, Zigbee, and proprietary 2.4 GHz protocols, as well as 802.15.4, Thread, Zigbee, and proprietary 2.4 GHz protocols.

The nRF52833 is the fifth member of the nRF52 Series SoC family, and it is based on a 64 MHz Arm Cortex-M4 with FPU, with 512 KB flash and 128 KB RAM memory for higher-value applications. The nRF52833 is a suitable device for a wide range of commercial and industrial applications, including professional lighting and asset monitoring, thanks to its expanded temperature range up to 105°C, a significant quantity of memory, and dynamic multiprotocol compatibility.  A 1:4 RAM to Flash ratio and +8 dBm output power make the nRF52833 suitable for advanced wearables or smart home applications where robust coverage is important.

A radio capable of Bluetooth® Direction Finding is included in the nRF52833. With Direction Finding, positioning solutions can rely on not just the received signal strength indicator (RSSI), but also the signal's true direction. This enhances precision and expands the range of applications available in this market. The angle of arrival (AoA), which calculates the direction of the received signal, and angle of departure (AoD), which calculates the direction of the transmitted signal, are the two sorts of methods for detecting direction.
