WELCOME TO ARADCONN

For a long time, Nordic Semiconductor's nRF52 series has been one of the most popular Bluetooth Low Energy (BLE) solutions on the market, known for its excellent balance. However, as application scenarios become increasingly complex, the demand for high performance and ultra-low power has grown. In response, Nordic has introduced the next-generation nRF54L series, heralding a generational leap in technology. This article will delve into a detailed comparison of the nRF54L and nRF52 series, analyzing the revolutionary advancements of the new chip from processing power and energy efficiency to overall design philosophy, and assessing how it is poised to redefine the design standards for future low-power IoT.

Bluetooth Channel Sounding (CS) and Bluetooth Angle of Arrival (AoA) / Angle of Departure (AoD) are both advanced technologies aimed at improving Bluetooth's ranging and positioning accuracy. However, they differ significantly in their underlying principles, applications, and advantages.

 Arad Connectivity Co., Ltd., today proudly announced that its innovative MN54L Series Bluetooth Low Energy (BLE) Module has successfully undergone stringent testing and achieved compliance with the U.S. Federal Communications Commission (FCC) Part 15.247 standard and Innovation, Science and Economic Development (ISED) Canada regulations. This achievement validates the module's international leading performance in wireless efficiency, stability, and regulatory compliance.

Unlike classic Bluetooth, which was designed for continuous, high-throughput data transfer, BLE's core philosophy centers on achieving extreme energy efficiency. This allows devices to communicate with minimal power consumption when only small amounts of data need to be exchanged, leading to battery lives extending for months or even years.

Arad Connectivity today proudly announced the official launch of its YouTube channel! This new platform will be your ultimate resource for the latest news and application insights on Bluetooth Low Energy (BLE) modules. Through a unique conversational format, we aim to make complex technological information easy to understand and apply.

Edge AI and Tiny Machine Learning (TinyML) aim to execute AI computations and data processing directly on devices near the data source, rather than relying on remote cloud servers. This approach offers lower latency, enhanced privacy, improved bandwidth efficiency, and greater reliability.

To take you deep into the BN52M-C32's key features, including its powerful nRF52832 core, flexible GPIO configuration, optimized low-power modes, and how to easily achieve stable Bluetooth communication. Whether you're developing IoT devices, smart sensors, or wearables, this article provides practical steps and valuable insights to help you turn your ideas into reality. My goal is to enable you to efficiently leverage the full potential of the BN52M-C32 and accelerate your development process.

Arad Connectivity’s BN52H-C40 Evaluation Board, powered by the Nordic nRF52840 SoC, features an integrated high-efficiency chip antenna and comprehensive I/O expansion interfaces. It serves not only as an ideal solution for development and testing but also as a crucial bridge to mass production.

The "Auracast" report by RNID (Royal National Institute for Deaf People) paints a compelling picture of how this new Bluetooth LE Audio standard can usher in a more inclusive world.

New Features of Arad Connectivity Official Website

Some customers outside the EU and USA have reported difficulties finding "Arad Connectivity" products on localized DigiKey websites (e.g., Korea site).
After investigating with DigiKey's team, we have identified that synchronization processes for multi-country platforms are still underway.

We are honored to be invited by the Taiwan Electrical and Electronic Manufacturers' Association (TEEMA) and Lipers Enterprise Co. Ltd (Nichidenbo Group) to participate in NEPCON Thailand 2025.

Bluetooth 5.4 introduces Periodic Advertising with Responses (PAwR), a feature designed to enhance efficiency in large-scale, low-power device networks. PAwR enables bidirectional communication within periodic advertising events, making it ideal for applications requiring synchronized, low-latency data exchange among many devices.

Arad Connectivity is excited to announce that its latest range of Bluetooth modules are available on DigiKey.
