Product Description

The WAVIoT RM-140 module is highly integrated, cost-effective, smart radio, sub-1 GHz wireless node solution composed of the integrated radio transceiver and a low-power ARM® Cortex M0+ CPU. The highly integrated RF transceiver operates over a wide frequency range including 868MHz, 915MHz in the license-free Industrial, Scientific and Medical (ISM) frequency bands. This configuration allows users to minimize the use of external components.

WAVIoT RM-140 is based on industry-leading low energy MCU, which allows ultra-low power consumption during the sleep cycle,  and significantly decreases active mode consumption for maximum power efficiency. WAVIoT RM-140 supports WAVIoT NB-Fi and conventional GFSK and ASK modulations for maximum compatibility and design flexibility.


  • Key benefits


    • NB-Fi proprietary LPWAN radio protocol
    • Best radio modem for smart metering
    • 16+ km range in harsh city environment
    • 20 years on AA battery
    • Low power is not sacrificing link budget
    • Option to embed user’s firmware into modem’s MCU
    • Data rate 11-100 bps via NB-Fi
    • Excellent jamming and interference immunity

  • Interfaces


    The WAVIoT RM-140 communicates with the host devices (MCU or PC) over AT serial interface.

    A simple set of commands is available for the developer to set various parameters such carrier frequency, data rate, etc. and sent useful data via WAVIoT or other supported protocols.

    15 GPIO lines can be configured as UART, SPI, I2C, ADC, PWM, etc. for interfacing with various sensors and external devices.
