Microchip SAMR34 Xplained Pro
The SAMR34 board is based on an Microchip SAM R34 Xplained Pro evaluation kit built on top of an Microchip ARM Cortex M0+ micro-controller. This board also provides a LoRa radio transceiver.
The SAMR34 board can reset, debug and program the ARM Cortex M0 through the embedded debugger (OpenOCD) connected to the gateway USB port. This component also allows a UART connection to the M0. The input power source is configured through the power management.
IoT-LAB special configuration
The serial connection baudrate should be configured at 115200 bauds in the firmware.
