Murata module CMWX1ZZABZ-091 development kit

BRKABZ01 Lora / Sigfox / Multi Zones

This BRKABZ01 Lora / Sigfox Development Kit is a prototyping tool for learning and developing IoT soliton based on the Murata CMWX1ZZABZ-091 all-in-one open module, covering the Lora / Sigfox and FSK prototypes.

The module is powered by a STM32L072CZ and a SX1276 transceiver. The transceiver is equipped with the LoRa® long-range modem, which enables ultra-long range extended spectrum communication and high immunity to interference, reducing power consumption.

The CMWX1ZZABZ-091 is an open module, so the user has access to all STM32L072 devices such as the analog-to-digital converter, the 16-bit timer, the LP-UART, the I2C, the SPI and the USB 2.0 FS ( supporting BCD and LPM).

The LoRaWAN ™ layer is certified to class A and C standards. It is available in the I-CUBE-LRWAN package. Several examples, including a stack of AT commands, are available to help users configure a complete LoRaWAN ™ object.

The Sigfox ™ layer is RCZ1, RCZ2 and RCZ4 certified. It is available in the X-CUBE-SFOX extension package. Several examples, including an AT command modem, are also available to help users configure a complete Sigfox ™ object.
