Avnet Silica has introduced Miromico LoRa transceiver modules to enable wireless connectivity to sensors, devices and systems communicating at high data rates or over a long distance.

The FMLR-8x-x-STLx LoRa and LoRaWan IoT modules are based on Semtech’s 2.4GHz technology.

Miromico partnered with Danalto to enable location services. The low-power modules connect wirelessly to sensors, devices and systems to communicate at high data rates or over long distances. Target IoT applications include track and trace, smart city, building, construction, mining and farming, telemetry, and remote data logging.

“Leveraging Miromico’s best in class devices which include the SX1280, Danalto has been able to move ahead with deploying this technology into sectors where an offering of this nature was not available until now,” said Albert Baker, COO of Danalto. “This has been ground-breaking for our customers and, with quality and timeliness in the delivery of hardware being so critical, Miromico has been able to support again and again.”

The modules support long-range time-of-flight (ToF) distance measurement and, because of their low power consumption and tiny footprint, are suitable for compact battery-driven applications.

The Arm Cortex M0+ or M4 32bit microcontroller runs complete RF stacks and has sufficient additional resources to run user applications, including edge computing, machine learning and AI. Designers can extend the system with low power sensors to build production-ready IoT sensor nodes.

“With our wireless module family concept, we provide the perfect support package for our clients,” said Alex Raimondi, director for embedded at Miromico. “Fast prototyping and cost competitive scale up are the key.”

The FMLR module is available with extra onboard flash memory to enable over-the-air (OTA) update and data storage. In addition to the long-range LoRa mode, the module supports high-bitrate modulation schemes such as GFSK, the robust and bandwidth-efficient FLRC and Bluetooth Low Energy for bidirectional communications with smartphones, tablets, gadgets and more.

Optional low-power high precision temperature compensated oscillators for both RTC and radio are also available. To support fast prototyping and development, the module’s firmware, including the wireless stack, can be updated via SWD, uart bootloader or optional OTA.

The IoT modules are shipping now from Avnet Silica in all Emea markets.

“Miromico is a key partner for Avnet Silica to drive the IoT strategy to the next level,” said Marco Giegerich, business development director for Avnet Silica. “With a wide variety of LoRa products such as modules, boards and finished devices, Miromico is providing essential building blocks for a highly scalable solution for customers working on innovative new LoRa-based IoT use cases.”
