Murata module CMWX1ZZABZ-091 development kit

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.

Attention, the whole radio layer Lora or Sigfox is to be develop using the librairy available on the STMicroelectronics website on the following link.
Good knowledge of progamation is necessary for its implementation.

A good tutorial example of the breakout board is available on the site www.disk91.com
