Ezurio (formerly Laird Connectivity), has released a family of Bluetooth LE modules based on Nordic Semiconductor’s new next generation of low power wireless SoC, the nRF54L15. The modules enable wireless product designers to bring new products to market faster, while delivering the highest level of performance, security and efficiency with ultra-low power consumption. The modules are predominantly designed for industrial, medical and commercial applications.

The ‘BL54L15 Series’ utilises the QFN48 package of Nordic’s nRF54L15 SoC. It features 31 GPIOs and comprises two module variants, that have either an integrated PCB trace antenna or a MHF4 connector on board. Both modules come in a 14 by 10 mm form factor.

The ‘BL54L15µ Series’ utilises the WSCLP package of the nRF54L15 SoC. It features 32 GPIOs and comprises two module variants that have either an integrated chip antenna or a trace pad for external antenna support. The modules come in a highly compact 6.3 by 7.9 mm form factor.

Efficient wireless communication

Each series of modules is optimised for high-performance applications, ensuring secure, robust and efficient wireless communication with support for the latest Bluetooth standards and secure programming options.

“The Bl54L15 and BL54L15µ module variants bring out the full capability of the market-leading, underlying Nordic silicon for the end customer to utilize in a fully pre-certified solution,” said Jonathan Kaye, the VP of product management and marketing at Ezurio. “The plethora of protocols and application support in a single hardware/software solution enables us to support the widest possible set of use cases and customer requirements for short range wireless connectivity.”

All variants within the Ezurio suite of products come with full regulatory certifications, pre-certified antennas, supporting development kits, and the company’s global support and service. In addition, Ezurio’s ‘Canvas Software Suite’ platform enables rapid development of embedded software applications using Python scripting with easy-to-use wireless APIs, tools, and sample code.

“Ezurio is a silver member of the Zephyr Project, so the fundamental building blocks of Nordic’s software architecture is a significant differentiator for us,” adds Kaye. “We’re also really excited about Nordic’s support for the new Bluetooth Channel Sounding feature set in the nRF54L Series.”

Powerful processing capabilities

The nRF54L15 features an Arm Cortex-M33 processor clocked at 128 MHz and an ultra-low power multiprotocol 2.4 GHz radio. It features enlarged memory up to 1.5 MB non-volatile memory (NVM) and 256 KB RAM, enabling support for advanced application software and wireless protocol stacks on a single chip, and eliminating the need for external MCUs or memory. The nRF54L15 integrates all standard peripherals enabling many products to be implemented with a single chip thus reducing the BOM cost. The SoC includes an integrated RISC-V coprocessor.

“The constant evolution of the Nordic silicon roadmap, and the flexibility and scalability of the Nordic nRF Connect SDK are enhanced further by the responsiveness of the commercial and support teams within Nordic. This combination makes Nordic stand out as the premier SoC vendor in the short-range wireless field,” concludes Kaye.
