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)
#define	XTIMER_HZ   (250000UL)
#define	XTIMER_BACKOFF   (40)
