UART configuration
This board does not have explicit UART pins. These are set as UART 0 to provide an easy serial debug port when not using (or debugging) USB.
#define	UART_0_ISR   (isr_uart0)
#define	UART_NUMOF   ARRAY_SIZE(uart_config)
static const uart_conf_t	uart_config []

PWM configuration
For the nRF52840-Dongle board, the PWM0 module is set to drive the LEDs LD1 and the channels LD2 red, green and blue in the four channels of PWM_DEV(0); other PWM outputs are not configured.
#define	PWM_NUMOF   ARRAY_SIZE(pwm_config)
static const pwm_conf_t	pwm_config []

SPI configuration
#define	SPI_NUMOF   ARRAY_SIZE(spi_config)
static const spi_conf_t	spi_config []

I2C configuration
#define	I2C_NUMOF   ARRAY_SIZE(i2c_config)
static const i2c_conf_t	i2c_config []
