Mingjiada Electronics imported original [Distribution NORDIC] Bluetooth IC NRF52811-CAAA-R7/NRF52811-QCAA-B-R7 Bluetooth 5.2 SoC supporting low power Bluetooth, Bluetooth direction finding and Thread protocol

NRF52811-CAAA-R7/NRF52811-QCAA-B-R7 Description:

The nRF52811 is a Bluetooth 5.2 SoC with multi-protocol support. nRF52811 is the 4th addition to the nRF52 family of platforms. It adds to an already rich platform that covers a wide range of applications and use cases.

The nRF52811 SoC features the latest and most powerful features of Bluetooth 5.1, most notably the direction finding function, which takes Bluetooth positioning to a whole new level.

The chip is based on an Arm® Cortex™-M4 processor clocked at 64 MHz. It has a number of digital peripherals and interfaces such as PDM, PWM, UART, SPI and TWI. it also has a 12-bit analogue-to-digital converter (ADC). Very low power consumption is achieved by using an advanced on-chip adaptive power management system.

The nRF52811 SoC supports a wide range of wireless protocols. It supports low-power Bluetooth with Bluetooth direction finding and positioning, as well as long range mode and 2 Mbps transmission rates. Thread and 2.4 GHz private protocols are also supported.
