DISCO-L072CZ-LRWAN1

The B-L072Z-LRWAN1 LoRa®Discovery kit is a development tool to learn and develop solutions based on LoRa®and FSK/OOK technologies.

Overview

The B-L072Z-LRWAN1 LoRa®Discovery kit is a development tool to learn and develop solutions based on LoRa®and FSK/OOK technologies. This Discovery kit features an all-in-one open module CMWX1ZZABZ-091 (by Murata). The module is powered by an STM32L072CZ and an SX1276 transceiver. The transceiver features the LoRa®long-range modem, providing ultra-long-range spread spectrum communication and high interference immunity, minimizing current consumption. Since CMWX1ZZABZ-091 is an open module, user has access to all STM32L072 peripherals such as ADC, 16-bit timer, LP-UART, I2C, SPI and USB 2.0 FS (supporting BCD and LPM).

The B-L072Z-LRWAN1 Discovery kit includes an ST-LINK/V2-1 embedded debug tool interface, LEDs, push-buttons, antenna, Arduino™Uno V3 connectors and USB OTG connector in Micro-B format.

Information

Only the labels written in blue/white or green/white (i.e. PA_4, PB_5, A0, D14, LED1...) must be used in your code. The other labels are given as information (alternate-functions, power pins, ...).

You can find more details on the available pins and labels in the following files (link to the latest mbed-dev library version):

Known limitations

The following section describes known limitations of the platform. Note that general issues are tracked into the mbed repository available on GitHub.

Warning

  • There is no AnalogIn on Arduino A1, A3, A4, A5 pins.
  • There is no PWM on Arduino D3, D5, D6, D9 pins.
  • In order to use Serial (TX and RX) on Arduino D0 and D1 pins, you have to remove SB28 and SB29 solder bridges. In this case you will lose the ST-Link connection.
