The Würth Elektronik Ophelia-IV compact, wireless module is built on the nRF54L15 SoC, offering flexible multiprotocol support and ultra-low power operation for next-generation IoT designs.
With its firmware free, developer focused platform, smart antenna options, and robust RF performance, it lets engineers build precisely the wireless solution they need. Whether creating a matter enabled sensor, a Zigbee industrial controller, or a fully customised IoT device, the Ophelia-IV provides the power, versatility, and scalability to bring innovative products to market faster.
The module supports Bluetooth LE 6, Matter, Thread, Zigbee, IEEE 802.15.4, NFC T, and proprietary 2.4GHz protocols, enabling broad interoperability across IoT ecosystems.
It is based on Nordic nRF54L15 SoC: Integrates a 128MHz Arm Cortex M33 processor, RISC V co-processor, and an ultra-low power 2.4GHz radio for high efficiency and performance.
The module is delivered without preinstalled firmware enabling a flexible ‘Build Your Own Firmware’ platform that provides full freedom to develop custom stacks using nRF Connect SDK and Zephyr RTOS
A smart antenna configuration features an integrated PCB antenna with an option for external antenna connection, allowing design flexibility and improved RF performance.
The module comes in a compact, IoT ready form factor: Ultra small 12 × 8 × 2.3 mm package ideal for space constrained designs, wearables, sensors, and industrial modules.
Applications cover industrial and commercial IoT, smart home and building automation, sensor networks and environmental monitoring and low power wireless devices.
The Würth Elektronik Ophelia-IV compact, high-performance wireless module is in stock at authorised distributor DigiKey.
