nRF52811System on chip

Bluetooth 5.2 SoC supporting Bluetooth Low Energy, Bluetooth Direction Finding and Thread

The nRF52811 is a Bluetooth 5.2 SoC with extensive protocol support. It is the 4th addition to the nRF52 Series platform, extending the numerous applications and use cases already covered by the platform.

The nRF52811 SoC is capable of the latest and greatest features of Bluetooth 5.1, the most prominent being Direction Finding, taking Bluetooth positioning to new heights.

It is built around a 64 MHz Arm® Cortex™-M4 CPU, and has a range of digital peripherals and interfaces such as PDM, PWM, UART, SPI and TWI. It also has a capable 12-bit ADC. Exceptionally low energy consumption is achieved using a sophisticated on-chip adaptive power management system. 

The nRF52811 SoC supports an extensive range of wireless protocols. It supports Bluetooth Low Energy, and is capable of Bluetooth Direction Finding in addition Long Range and 2 Mbps. Thread, and 2.4 GHz proprietary protocols are also supported. It has 4 dBm TX power and has been optimized to offer the best RX sensitivity of all SoCs in the nRF52 Series:

  • Bluetooth LE - Long Range: -104 dBm
  • Bluetooth LE - 1 Mbps: -97 dBm
  • Thread:       -101 dBm


The nRF52811 SoC is supported by the nRF5 SDK, providing examples, libraries and drivers to get started. nRF5 SDK for Thread and Zigbee offers limited Thread support.

The nRF52840 DK is the recommend development kit, emulating the nRF52811 SoC, and can be used as a starting point for development before moving over to a custom board. Please note that this development kit does not support Bluetooth Direction Finding.

The nRF52811 SoC comes in our smallest package, a 2.48x2.46 mm WLCSP package, together with two QFN packages. It is drop-in compatible with the nRF52810 SoC in all package variants:

  • 6x6 mm QFN48 with 32 GPIOs
  • 5x5 mm QFN32 with 17 GPIOs
  • 2.48x2.46 mm WLCSP32 with 15 GPIOs

Development kit

Evaluate, prototype and develop with the nRF52811 SoC

nRF52840 DK

The nRF52840 DK is a Bluetooth LE, Bluetooth mesh, Thread and Zigbee development kit for the nRF52811 and nRF52840 SoCs.

Software development kits

nRF5 SDK

The Bluetooth LE and ANT software development kit

The nRF5 SDK is a high quality, thoroughly tested software development kit to accelerate your software development efforts for the nRF52 and nRF51 Series SoCs. It contains hundreds of useful firmware modules and examples to assist in building your application.
 

nRF5 SDK for Thread and Zigbee

nRF5 SDK for Thread and Zigbee is a complete solution  for building Thread 1.1 and Zigbee 3.0 certified products. It utilizes the the multiprotocol capabilities of the nRF52833 and nRF52840 wireless SoCs. This enables single-chip application development supporting both Bluetooth LE and Thread or Zigbee, concurrently. It also has limited support for the nRF52811.
