Ezurio Launches BL54LM20 Series with Edge AI for Scalable IoT Connectivity

24 September 2026 | NEWS

New pre-certified modules combine Nordic Semiconductor SoCs, expanded memory and I/O, USB connectivity and integrated NPU-based Edge AI for next-generation low-power IoT devices.

Ezurio, a global leader in connectivity and embedded compute technology, announces the BL54LM20 Series: the BL54LM20A, BL54LM20B, and BL54LM20B USB-C Adapter. Built on Nordic Semiconductor's new nRF54LM20A and nRF54LM20B SoCs, the BL54LM20 Series brings USB, more memory, more I/O, and, for the first time in the BL54L family, module-level Edge AI capability to market.

Pairing a 128 MHz Arm Cortex-M33 application processor with a 128 MHz RISC-V coprocessor, 2 MB of non-volatile memory, and 512 KB of RAM, the BL54LM20 Series gives designers substantially more headroom for larger applications, richer protocol combinations, and long-term product scalability. The pre-certified series delivers an expanded IO set, multiple pre-certified antennas, and the security, size, and time-to-market advantages developers expect from the BL54L line.

The BL54LM20A and LM20B are 100% footprint-compatible and share the same RF design and certification - start a design on one, move to the AI-enabled variant later without a board respin or a new certification cycle.

"The BL54LM20 Series extends Ezurio's BL54L lineup, giving customers a complete, scalable range of pre-certified modules to match almost any performance or footprint requirement," says Jonathan Kaye, VP of Product Management and Marketing at Ezurio. "The BL54LM20A covers customers who just need more flash, RAM, and I/O, while the BL54LM20B adds an integrated NPU for teams ready to bring Edge AI on board. Either way, developers get a scalable path forward on the same pre-certified module footprint our BL54L customers already trust."

"Nordic's Axon NPU was built to bring real machine learning performance to a wide range of ultra-low-power IoT devices," said Sam Presley, Technical Product Manager at Nordic Semiconductor. "Ezurio's BL54LM20B shows exactly what that looks like in the field: a pre-certified module that gives developers up to 15x faster on-device inferencing without asking them to become NPU experts first."

BL54LM20A: USB, More Memory, More I/O, More Flexibility

  • Powered by Nordic nRF54LM20A SoC delivering Bluetooth LE Core 6.x, 802.15.4 (Thread/Matter), and NFC in a single 11 × 8 × 1.8 mm module
  • 128 MHz Arm Cortex-M33 application processor + 128 MHz RISC-V coprocessor, 2MB non-volatile memory and 512 KB RAM
  • Expanded IO set for more sensors and peripherals, richer HMIs, and gateway-class or controller-style designs
  • Secure Boot, Secure Firmware Update, Secure Storage

BL54LM20B: Adds Edge AI Built-In

  • Integrated Axon NPU delivers up to 15x faster AI inferencing than CPU processing alone
  • Real-time, offline AI/ML inference with no dependency on cloud connectivity and improved power efficiency for always-on ML tasks
  • Access to Nordic's Edge AI Lab and pre-trained Neuton models to help developers build and deploy on-device AI models quickly

BL54LM20B USB-C Adapter

The family also includes a USB-C Adapter, which embeds the certified BL54LM20B module in a compact final product, ideal for adding to gateways, PCs, internal development and production rigs. Importantly, the adapter is regulatory certified enabling customers to reduce their risk and cost and get to market faster.

With Edge AI, ultra-low-power Bluetooth LE, Thread/Matter, and NFC in one module, the BL54LM20 series is ideal for a broad range of connected products, including predictive maintenance sensors, wearable and portable medical devices, factory automation and robotics, asset tracking, and smart building and commercial IoT devices that need to make decisions locally and securely.
