This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.

Nordic Semiconductor Bluetooth Direction Finding SoCs

Nordic Semiconductor’s nRF52811 Bluetooth 5.1 Direction Finding SoCs enable precise Bluetooth position finding for real-time location systems, asset tracking, smart home devices, and more. 

The nRF52811 SoC includes support for angle-of-arrival and angle-of-departure direction-finding acting as either the transmitter or receiver and can control up to 8 GPIOs for external antenna switching. The transceiver supports data rates up to 2 Mbps, can be used with other 2.4GHz protocols, and has high transmit power and sensitivity.

It features a 64MHz Arm Cortex-M4 CPU with 192kB of Flash, 24KB of RAM, a 12-bit ADC, and a full range of interfaces with EasyDMA. It also has an integrated regulator and adaptive power management to minimize power consumption.

    Cannot wait to try out the direction finding capabilities. Just a note, I think it should be ‘Supports AoA and AoD’ , I see AoD twice here and in the video.
