FMLR-61-MAX

FMLR-61-MAX is the world's smallest LoRa^® and LoRaWAN^® IoT module, measuring just 7.4mm by 8.2 mm, making it the ideal choice when space is at a premium. Powered by a Semtech SX1261 chipset, this module provides wireless connectivity to devices and sensors operating in the sub-GHz spectrum, covering frequencies from 150 MHz to 960 MHz and supporting all major sub-GHz ISM bands worldwide. With an impressive 163 dB link budget, it maintains a constant RF output of +15dBm and boasts high sensitivity down to -148 dBm. Additionally, alongside LoRa modulation, the module supports (G)FSK modulation for legacy use cases.

Thanks to its low power consumption, the FMLR-61-MAX is perfect for applications requiring small-sized batteries. It features an integrated Analog Devices MAX32625 MCU, housing a low-power 32-bit ARM Cortex-M4 microcontroller with FPU, 128 kB flash and 128 kB RAM. For applications demanding heightened security, a variant with the MAX32626 is also available, offering a Trust Protection Unit (TPU), a True Random Number Generator, and a Secure Boot Loader – providing all the necessary tools to develop the next generation of secure IoT devices.
