Functional Description
The FMLR-72-x-STL0Z is a compact low-power wide-area network (LPWAN) wireless module that
supports the LoRaWAN long-range wireless protocol.
The external antenna module measures just 14 x 19.5 mm or 14 x 22.75 mm in the chip antenna variant.
This makes it an extraordinarily small LoRa Module with an integrated antenna. The module includes a
Semtech SX1272 ultra-long-range spread-spectrum wireless transceiver and an STM32L0Z series ARM
Cortex M0+ 32 bit microcontroller (MCU) with an internal flash size of 192 kB.
It is capable of sending with up to 20 dBm and receiving with a sensitivity of -137dBm. This allows the
module to be placed in high density urban or long range rural environments and connect a large variety
of sensors to LoRaWAN and proprietary networks based on LoRa, (G)FSK, (G)MSK, ASK, OOK coding
schemes. Examples are Wireless M-Bus, IEEE802.15.4g, Nordic NRF905 and NRF9E5 emulation.
