Overview

The nRF52833-QDAA-R is a versatile multiprotocol SoC designed for Bluetooth 5.1 Direction Finding and high-performance wireless applications. It features a 64 MHz Arm Cortex-M4 with FPU, 512 KB Flash, and 128 KB RAM, making it capable of handling complex networking stacks alongside user applications. The integrated Full-speed USB and wide supply voltage range up to 5.5V simplify power delivery and connectivity in portable designs.

Why Choose This Part

The nRF52833 bridge the gap between the nRF52832 and nRF52840, offering a significant 128 KB RAM and Full-speed USB in a cost-optimized package. Its wide 1.7V to 5.5V supply range allows for direct operation from Li-Po batteries or USB power, while the integrated balun reduces PCB complexity and component count.

Applications

Bluetooth Direction Finding
Utilizes Angle-of-Arrival (AoA) and Angle-of-Departure (AoD) support for high-accuracy indoor positioning and asset tracking.
Industrial Mesh Networking
Supports Bluetooth mesh, Thread, and Zigbee for robust, scalable sensor networks in industrial environments.
Advanced Wearables
Leverages the low 4.8 mA TX current and 128 KB RAM to support sophisticated wearable sensors with long battery life.
USB Peripherals
Integrates a 12 Mbps USB controller for direct connection to PCs and charging interfaces without external bridge chips.

Getting Started

Developers should use the nRF Connect SDK, which integrates the Zephyr RTOS for modern firmware development. Hardware evaluation is best performed using the nRF52833-DK development kit, which provides access to all 32 GPIOs and features an onboard SEGGER J-Link debugger. The chip supports over-the-air (OTA) firmware updates and includes an NFC-A tag for simplified Bluetooth pairing.
