LoRa module is built around Renesas’ Synergy platform
Together with Miromico AG, Renesas Electronics has developed the compact and low-power FMLR-61-x-RSS3 module based on LoRa devices and wireless radio frequency technology. The new Miromico module enables customers to connect easily to LoRaWAN-based networks that are mushrooming across Europe.

The 14.2x19.5mm board employs Renesas’ Synergy platform, giving customers access to microcontrollers (MCUs) and a large production-grade software package. Engineers can use the S3A6 MCU on the LoRa-based module to handle various tasks, while seamlessly streaming data across a LoRaWAN-based network to the cloud. The LoRaWAN protocol is quickly becoming the de facto standard to connect the “Things” of the Internet of Things (IoT) across long distances (up to 50km), flexibly and securely, while keeping batteries alive for years. The FMLR-61-x-RSS3 operates from 1.8 to 3.3V, and the module’s power consumption ranges from just 1.4uA in sleep mode to 25.5mA (typical) in TX mode (14dBm). Receiver sensitivity is -148dBm in LoRa mode SF12 at 10.4 kHz, and the module’s operating temperature range is -40 to 85°C. The FMLR-61-x-RSS3 module employs the S3A6 MCU with integrated 48 MHz Arm Cortex-M4 core, and features 256 KB code flash memory, 8 KB data flash, and 32 KB SRAM, which is enough memory to allow engineers to add a variety of their own functions. Most MCU signals are available at the module level to make them externally accessible.
