Wireless M-Bus & LTE Cat 1 sensor board also supports Zigbee 3.0, Z-Wave, Bluetooth LE 5.0, LoRa…

Geniatech SCB32IM is a sensor board based on Silicon Labs EFR32FG14 Arm Cortex-M4 microcontroller with a sub-GHz radio enabling wireless M-Bus (Wireless Meter Bus) designed for remote reading of smart meters, and also equipped with a Quectel EC200S “IoT/M2M-optimized” LTE Cat 1 module.

The sensor module does not actually come with any sensor on board, but provides a terminal block to connect any sensor you may need for your product. It’s also possible to extend wireless connectivity options with Zigbee 3.0, Z-Wave, Bluetooth LE 5.0, LoRa, and more through the GT-IoT interface with UART, SPI, and one GPIO.
