Overview

The NINA-B306-00B is a compact u-blox Bluetooth Low Energy module based on the Nordic nRF52840 SoC. It provides Bluetooth v5.0 connectivity with an integrated trace antenna, industrial-grade design, and global regulatory coverage for easier product certification. The module exposes common serial and peripheral interfaces for sensors and host MCUs.

Why Choose This Part

The NINA-B306-00B combines the feature set of Nordic's nRF52840 (powerful Cortex-M4F MCU and Bluetooth 5.0 PHY) with u-blox's module-level testing and global regulatory coverage, reducing certification effort. Its integrated trace antenna and 10 dBm transmit power with -100 dBm sensitivity provide robust link budget in compact designs. Exposed interfaces (UART, SPI, I2C, I2S, USB, GPIO, ADC, PWM) simplify integration with sensors and host systems.

Applications

Battery-powered IoT sensors
Low-power BLE links for sensor telemetry, asset tracking, and remote monitoring.
Wearables and health devices
Compact module size and integrated antenna suit small form-factor consumer and medical wearables.
Industrial wireless peripherals
Industrial-grade module with global regulatory support for factory automation and instrumentation.
Audio and accessory control
BLE connectivity for remote controls, audio accessories, and human-interface devices.
Gateway and edge nodes
Use as a BLE endpoint in gateways or edge devices that bridge sensor networks to cloud services.

Getting Started

Start by reading the u-blox NINA-B306 datasheet and reference designs for recommended layout and antenna keepouts. For firmware, use Nordic's nRF Connect SDK or Zephyr (both support nRF52840) and program/debug via an SWD probe (for example a SEGGER J-Link) or by using a u-blox development board if available. Use common toolchains like GCC with Segger Embedded Studio or arm-none-eabi toolchain and test RF performance with the module mounted on a representative PCB.

Also Consider
