I. ROHM EnOcean Passive Wireless Communication Modules

ROHM EnOcean modules are self-powered wireless communication modules developed in accordance with the ISO/IEC 14543-3-10/11 international standard. Their core advantage lies in the fact that they require neither batteries nor an external power supply; instead, they generate their own power and transmit wireless signals using mechanical energy and ambient light. This completely resolves the industry pain points associated with traditional wireless modules—such as dependence on power sources, battery replacement and cumbersome maintenance—making them a core component for green, passive IoT applications.

Key Product Features

- Self-powered with zero operational and maintenance costs: Equipped with ROHM’s proprietary electromagnetic induction power generation component (ECO 200), it generates power and transmits signals using mechanical kinetic energy such as pressure or vibration. With no wiring or batteries required, it is suited to long-term, maintenance-free operating scenarios, significantly reducing the device’s long-term operational and maintenance costs.

- Minimalist integration design: The module features a built-in, factory-fitted antenna, eliminating the need for customers to undertake additional high-frequency circuit design and antenna matching. This simplifies the hardware development process, shortens project implementation cycles and lowers the barrier to entry for R&D.

- Comprehensive compliance certification: The entire product range is certified under Japan’s Radio Wave Act and supports compliant use of the 928 MHz specific low-power wireless frequency band. It is also compatible with mainstream global RF regulations, enabling direct use in the mass production of commercial and industrial-grade terminal devices.

- Stable, interference-resistant and reliable transmission: Utilising the proprietary EnOcean wireless communication protocol, these modules offer excellent resistance to radio frequency interference. They deliver stable communication signals and extremely low power consumption, making them suitable for wireless communication scenarios involving dense device deployments and complex electromagnetic environments.

Core Application Scenarios

Widely used in IoT terminal devices that require no power supply or maintenance, such as smart passive switches, building lighting automation systems, door and window status sensing and monitoring, passive touch switches for industrial equipment, wireless control systems for smart hotels, and smart retrofitting of older buildings.

II. ROHM Bluetooth Low Energy (BLE) Modules

ROHM’s Bluetooth Low Energy modules (MK71511(A) and MK71521(A) series) are ultra-low-power, single-mode wireless communication modules developed in accordance with the Bluetooth 5.2 core specification. They are meticulously engineered by ROHM’s subsidiary, LAPIS TECHNOLOGY, The entire range has passed official Bluetooth SIG component certification and, combined with the proven Nordic protocol stack, offers the core advantages of low power consumption, high integration, broad compatibility and full certification, making them the preferred wireless communication solution for consumer electronics, industrial IoT and smart wearable devices.

Key Product Features

- Ultra-high integration, simplified mass production: A fully integrated, monolithic design incorporating a complete set of core components—including an internal antenna, RF peripheral circuits and memory units—eliminates the need for additional peripheral components. It supports dual-layer, low-cost PCB mounting, effectively reducing customers’ overall production costs and hardware footprint.

- Ultra-low power consumption, long battery life: Optimised design based on the BLE low-power architecture significantly reduces standby and operating power consumption, making it suitable for battery-powered portable terminals and sensor devices, and greatly extending the device’s battery life.

- Performance tailored to specific applications: The MK71511(A) is designed for lightweight, general-purpose scenarios, meeting standard Bluetooth data transmission requirements; the MK71521(A) is equipped with 512KB of high-capacity FLASH memory and supports the establishment of Bluetooth mesh networks, making it suitable for complex networking and multi-device coordination in IoT scenarios. Both products are fully pin-compatible and have identical form factors, allowing for seamless replacement and upgrades.

- Multifunctional expansion: The module features built-in high-precision orientation detection, supporting extended applications such as high-precision indoor positioning and device attitude recognition, and meeting the diverse development needs of smart devices.

- Global Compliance Certification: The entire product range has passed authoritative certifications in multiple countries, including FCC (USA), ISED (Canada), CE (EU) and the Japanese Radio Wave Act, and complies with the latest EN 300 328 wireless testing standard. Customers do not require secondary RF certification and can proceed directly to global mass production and distribution.

Core Application Scenarios

Suitable for a wide range of Bluetooth IoT applications, including smart wearable devices, Bluetooth sensor terminals, smart home networking devices, indoor positioning modules, industrial low-power data acquisition terminals, portable smart hardware and wireless remote control devices.
