LOB900C: Wireless M-Bus & LoRa module

Compact SMD module with Lobaro wMBUS & LoRaWAN Multi Stack Firmware

The Lob900C radio module

Wireless M-Bus (wMBUS, Meter-Bus) is a widely used European standard (DIN EN 13757-4) in the field of smart metering. Many gas, water, electricity and heat meters can already be recorded and various actuators controlled using Wireless M-Bus. The type of sensor to be queried is not limited and Wireless M-Bus is also used for humidity/temperature sensors, pulse converters and analog/digital converters.

Thanks to the special Lobaro firmware, we can offer you the LOB900C, an energy-saving wireless module especially for the above-mentioned application scenarios in (sub)metering. Thanks to our Lobaro multi-stack firmware, we can integrate it into your application scenario in the shortest possible time. Standard applications include the reception of wMBUS telegrams and downstream retransmission via a LoRaWAN network. But uploading via mobile networks (2G, LTE, NB-IoT) is also no problem with the LOB900C & a GSM modem!

The module is equipped with a powerful 32-bit Cortex-M3 processor in combination with the Semtech SX1272 Radio transceiver via which customer-specific firmware solutions can be implemented thanks to the Lobaro multi-stack firmware.

Supported wireless technologies & protocols:

  • Lobaro LoRa Point to Point (P2P) on LoRa basis
  • LoRaWAN (Wideband)
  • wMBUS reception of S, C and T-mode devices (standard FSK)
  • SigFox (Ultra Narrowband)


Lobaro not only provides the hardware, but can also help you with the Installation, data acquisition and evaluation.

The data acquisition can be customized to your application. Short or long-term monitoring, different measuring intervals, ... we help you to find the right parameters.

Our customers regularly benefit from improvements to the hardware, as the basic elements of the Lobaro box is also regularly expanded and improved in other projects.
