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.
