WAVIoT RM-141 Development Kit

  • Request for the price

    RM141 is devkit for very long-range solution IoT solution development. Allows to developers to design, program and evaluate their applications using Axsem NB-Fi pre-programmed radio chips under real world conditions. Sending and receiving messages is done via AT commands.


Long-range IoT development kit for the smart solution development such as smart water metering, smart grids, remote sensing monitoring etc. The devkit is complete with 1.9 dBi dipole antennas.

RM141 devkit is development and evaluation platform which serve three main purposes:

  • PER (Packet Error Rate) demo: out of the box range testing demo (plug and play) provides a quick test of product capabilities, with one-way packet transfer.
  • RF evaluation: in a test bench environment, connect to RF equipment and evaluate the product performance: power, sensitivity, current consumption, etc.
  • Design facilitator: use the RF module to start developing the application (power supply, software), before the actual form-factored customer PCB is ready and stabilized.

This development kit consists of the following individual parts:

    • PCB antennas
    • Display
    • EFM Happy Gecko
    • Axsem NB-Fi pre-programmed
    • USB
    • 2 LEDS
    • 4 buttons
    • 32 kHz TCXO
