EMB-LR1272 / EMB-LR1272E

868 / 915 MHz
LoRa® / LoRaWAN® module





  • Description

    EMB-LR1272 / EMB-LR1272E  is a 868 / 915 MHz wireless module that combines high performance to small dimensions and low cost, providing the system integrator a simple and easy way to add LoRa® / LoRaWAN® long range connectivity into existing products.

    Notable features include:

    • output power can be set up to +19 dBm (~80 mW) or to +14 dBm (~25 mW)
    • sensitivity up to -137 dBm
    • extremely reduced power consumption in low power mode (≤3 μA in with a RTC clock running, ≤1 μA in XLP sleep (contact us))
    • embedded IEEE EUI-64 address (EMB-LR1272E)
    • open platform

    The EMB-LR1272 modules is provided with a embedded LoRa®/LoRaWAN® stack specifically developed by Embit that allows to be compliant with the latest LoRaWAN® specifications, allowing customer to develop firmware application and manage a compatible LoRa® eco-system.

    The EMB-LR1272 modules ship programmed with EBI-LoRa which allows the customer to use the modules as a simple, ready-to-use modem (using AT-like commands over UART; see EBI protocol page for more information). The evaluation kit EMB-LR1272-EVK is strongly suggested to customers willing to develop their own firmware applications, since the kit provides all tools required to download a custom firmware on the module.

    Please note that the EMB-LR1272E is available in 2 versions :
    EMB-LR1272E/PC – Pad connector
    EMB-LR1272E/UL – with micro U.FL connector for external antenna.
