FMLR-

8X-X-STX

HIGH PERFORMANCE COMBINED 2.4 GHZ LORA

IOT MODUL

FMLR 2.4 GHz low power

wireless module with

STM32L0 or STM32L4 MCU,

time-of-ﬂight ranging, BLE

5.0 stack

FMLR-8X-X-STX LoRa

IoT modules enable

devices and sensors to communicate at high

data rates or over long-distance in the world-

wide available 2.4 GHz ISM spectrum. The

modules also support time-of-ﬂight (ToF) dis-

tance measurement for indoor and outdoor lo-

calization. Power consumption can be opti-

mized to run on a small-sized battery. The MCU

has plenty of resources available to run even

the most advanced and demanding wireless

stacks and user applications with precise timing,

edge sensor computation, consolidation, local

storage and more. The FMLR module supports

additional modulation schemes such as high-bi-

trate long-range FLRC. Demos and stacks for

LoRa 2.4 GHz, TDMA available on request.

Recommended Soldering Conditions The following graph shows a typical temperature profile for the module soldering process. The exact values to be used in production are highly dependent on other parameters of the soldering process, such as soldering paste, PCB design, soldering process, etc. Reflow process should be finished within 2 cycle.
