STDIO configuration
As the CPU is too slow to handle 115200 baud, we set the default baudrate to 9600 for this board
#define	STDIO_UART_BAUDRATE (9600U)

Usage of LED to turn on when a kernel panic occurs.
#define	LED_PANIC LED0_ON

CPU clock scale for arduino boards
#define	CPU_ATMEGA_CLK_SCALE_INIT CPU_ATMEGA_CLK_SCALE_DIV1

xtimer configuration values
#define	XTIMER_WIDTH (16)
