Miromico FMLR-61-STM LoRaWAN® Modules.
FMLR-61-STM are LoRa® and LoRaWAN® IoT modules built on Semtech’s SX1261 chipset. They offer wireless connectivity to devices and sensors operating in the sub-GHz spectrum; spanning frequencies from 150 MHz to 960 MHz and supporting all major sub-GHz ISM bands worldwide. Offering an impressive 163 dB link budget; the modules support a constant RF output of +15 dBm and exhibit high sensitivity down to -148 dBm. Alongside LoRa modulation; G)FSK modulation for legacy use cases is supported.
Thanks to their low power consumption; the modules are ideal for applications utilizing small batteries. Applications can run on the integrated STM32L0 MCU; featuring a low-power 32-bit ARM Cortex®-M0+ microcontroller with 192 kB flash and 20 kB RAM. For more demanding IoT applications; an STM32L4 MCU is also available; featuring a low-power 32-bit ARM Cortex-M4 microcontroller with FPU; 512 kB flash; and 160 kB RAM. The STM32L4 variant offers sufficient RAM to support LoRaWAN firmware over-the-air (FUOTA) updates.
