I. ROHM EnOcean Energy-Harvesting Wireless Modules

1. Core Technical Principles and Standards

EnOcean modules are passive wireless communication modules based on energy harvesting technology. Their core advantage lies in eliminating the need for batteries or external power sources; instead, they rely on micro-energy from the environment to achieve self-powering and data transmission, fully aligning with the development needs of the passive Internet of Things (IoT). These modules comply with the ISO/IEC 14543-3-10/11 international wireless standard and represent an industry-standardized passive wireless communication solution, offering exceptional compatibility and versatility.

The module can harvest various types of low-level energy from the environment, including mechanical energy from button presses, thermal energy from ambient temperature differences, and light energy from natural indoor lighting. Through a built-in micro-energy conversion chip, it converts this low-level energy into electrical power to support a single wireless data transmission, truly achieving battery-free, wireless, and zero-maintenance wireless communication.

2. Frequency Band Specifications and Compliance Features

ROHM’s EnOcean modules employ a region-specific frequency band design to comply with radio regulations in different regions worldwide, avoid frequency interference, and ensure communication stability: the 868 MHz band is used in Europe, the 902 MHz band in North America, and the 315 MHz/928 MHz dual-band configuration in Japan. The 928 MHz model fully complies with Japan’s regulations for specific low-power radio stations, has completed official certification, and is ready for immediate deployment.

The products feature built-in antennas, eliminating the need for users to design high-frequency circuits or perform antenna matching and debugging. This significantly lowers the hardware development barrier, simplifies the end-product design process, and shortens the project R&D cycle.

3. Core Products and Performance Advantages

ROHM’s EnOcean core modules include mainstream models such as the PTM215B and PTM216B. The next-generation PTM216B module features enhanced performance, with wireless transmission power doubled compared to the previous generation, providing broader network coverage and stronger signal penetration to accommodate complex operating environments. Additionally, some models integrate an NFC interface, supporting convenient pairing, parameter configuration, and device debugging, thereby enhancing the product’s smart adaptation capabilities.

Summary of Core Advantages:

- Passive and Maintenance-Free: Requires no batteries or external power sources, eliminating issues such as battery replacement, leakage, and aging, and significantly reducing long-term operational and maintenance costs, making it suitable for long-term unattended scenarios;

- Ultra-low power consumption for optimal adaptation: High energy harvesting efficiency allows communication to be triggered by even the faintest ambient energy, with standby power consumption approaching zero;

- Minimal deployment: Built-in antennas eliminate the need for high-frequency design, simplifying hardware and software integration and enabling rapid mass production and deployment;

- High stability and interference resistance: Dedicated narrowband frequency communication ensures strong resistance to environmental interference and high data transmission accuracy.

4. Primary Application Scenarios

Leveraging its passive, wireless, and long-life characteristics, the EnOcean module is primarily designed for smart control and sensing networks in fixed environments. Its core applications include smart buildings and building automation, such as passive smart switches, lighting control systems, door and window status sensors, passive temperature and humidity data loggers, and building security sensors. They are also suitable for passive point monitoring and equipment status feedback in industrial automation scenarios, as well as for the smart retrofitting of older buildings (enabling rapid upgrades to smart control systems without the need for rewiring).

II. ROHM Bluetooth Low Energy (BLE) Modules

1. Technical Positioning and Version Specifications

ROHM’s Bluetooth Low Energy (BLE) modules are wireless communication modules designed for general-purpose, short-range IoT applications. They emphasize ultra-low power consumption, high-speed networking, and universal compatibility. The entire product line is developed based on the Bluetooth 5.2 PHY standard and consists of standardized components that have undergone full certification by the Bluetooth SIG. After integrating these modules, users do not need to undergo additional Bluetooth certification and can proceed directly to mass production of end devices, significantly reducing certification costs and lead times.

Compared to traditional Bluetooth, BLE modules eliminate redundant high-speed transmission capabilities and focus on the IoT requirements of low data rates, low power consumption, and long standby times. By balancing communication efficiency with energy-saving features, they serve as the mainstream wireless networking solution for consumer electronics and smart devices.

2. Core Products and Technical Features

ROHM’s mainstream BLE modules include classic models such as the MK71511 and MK7152. These modules integrate RF circuits, baseband chips, and peripheral matching circuits into a streamlined, monolithic design, featuring a compact form factor suitable for miniaturized end products. The modules support Bluetooth Mesh networking, enabling interconnectivity among multiple devices to build large-scale networks of end devices, while also supporting various functional modes such as precise positioning, data passthrough, and device interconnection.

Core Technical Features:

- Ultra-low power consumption: Optimized chip sleep and wake-up mechanisms significantly reduce standby and transmission power consumption, making them suitable for battery-powered devices and effectively extending battery life;

- Full compatibility and certification-free: Compliant with the Bluetooth 5.2 standard, compatible with all mainstream smartphones, gateways, and control devices; SIG pre-certified to facilitate rapid time-to-market;

- Versatile Support: Supports three core functions—data transmission, location services, and device networking—to accommodate diverse terminal scenarios;

- Highly Stable Transmission: Optimized RF anti-interference algorithms ensure stable transmission on the 2.4 GHz general-purpose frequency band, with fast network response times and extremely low latency.

3. Core Application Scenarios

ROHM’s Bluetooth Low Energy modules are highly versatile, covering multiple fields including consumer electronics, smart wearables, security, industrial applications, and retail. In the consumer sector, they can be used for fitness and sports equipment, health-monitoring wearables, smart remote controls, and smart home device networking; in the commercial sector, they support location services such as POI (Points of Interest) positioning, asset tracking, and personnel tracking; in the industrial and security sectors, they can be used to build small-scale device control networks and smart security monitoring systems, enabling real-time uploading of device status and remote linked control.
