st-lrwan1 LoRa RIOT Contiki-NG Zephyr Lille 5 Saclay 20

The B-L072Z-LRWAN1 board is LoRa capable board running on ab ARM CortexM0+ STM32L072CZ microcontroller.

It is possible to reset, debug and program the ARM Cortex M0 through the embedded debugger (ST-LINK) connected to the gateway USB port. This component also allows a UART connection to the M0.

IoT-LAB special configuration

The serial connection baudrate should be configured at 115200 bauds in the firmware and use USART2 on pins PA3 (RX) and PA2 (TX).

Sensors extension

Nodes are deployed with Sensor Expansion Board for STM32 Nucleo Board: ST X-NUCLEO-IKS01A2 & ST X-NUCLEO-IKS01A3

Nodes equipped with the ST X-NUCLEO-IKS01A2:

  • Saclay site (st-lrwan1-1 to st-lrwan1-20)
  • Lille site (st-lrwan1-1 to st-lrwan1-2)

Nodes equipped with the ST X-NUCLEO-IKS01A3:

  • Lille site (st-lrwan1-3 to st-lrwan1-5)

The ST X-NUCLEO-IKS01A2 shield gives access to external sensors to the nodes:
