DESCRIPTION

REFERENCE (Pin

designation)

I2C_SCL

(Master)

Master I2C Clock Line

[N] P0.28

GPIO_23

DIO

General purpose I/O pin.

[N] P0.23

GPIO_13

DIO

General purpose I/O pin.

[N] P0.13

UART_RX

[N] P0.11

READY

Generated interrupt from the device.

Indicates events such as SPI data ready, or

location data ready.

See the function dwm_int_cfg() in the DWM1001

Firmware API Guide for details[5].

[N] P0.26

UART_TX

UART_TX, This is also the ADC function of the

nRF52

[N] P0.05

GPIO_1

DIO

General purpose I/O pin of the DW1000.

It may be configured for use as a SFDLED

driving pin that can be used to light a LED when

SFD (Start Frame Delimiter) is found by the

receiver. Refer to the DW1000 User Manual [1]

for details of LED use.

[DW] GPIO1

GPIO_0

DIO

General purpose I/O pin of the DW1000.

It may be configured for use as a RXOKLED

driving pin that can be used to light a LED on

reception of a good frame. Refer to the

DW1000 User Manual [1] for details of LED use.

[DW] GPIO0

GPIO_15

DIO

General purpose I/O pin.

[N] P0.15

GPIO_8

DIO

General purpose I/O pin.

[N] P0.08

SPIS_MISO

Configured as a SPI slave this pin is the SPI

data output. Refer to Datasheet for more details

[1].

[N] P0.07

SPIS_MOSI

Configured as a SPI slave this pin is the SPI

data input. Refer to Datasheet for more details

[1].

[N] P0.06

SPIS_CLK

Configured as a SPI slave this pin is the SPI

clock. This is also the ADC function of the

nRF52

[N] P0.04

SPIS_CSn

Configured as a SPI slave this pin is the SPI

chip select. This is an active low enable input.

The high-to-low transition on SPICSn signals the

start of a new SPI transaction. This is also the

ADC function of the nRF52

[N] P0.03

GPIO_3

This pin is configured for use as a TXLED

driving pin that can be used to light a LED

during transmit mode. Refer to the DW1000

User Manual [2] for details of LED use.

[DW] GPIO3

GPIO_2

This pin is configured for use as a RXLED

driving pin that can be used to light a LED

during receive mode. Refer to the DW1000

User Manual [2] for details of LED use.

[DW] GPIO2

BT_WAKE_UP

When this pin is asserted to its active low state

the Bluetooth device will advertise its availability

for 20 seconds by broadcasting advertising

packets. This is also the ADC function of the

nRF52.

[N] P0.02

RESETn

Reset pin. Active Low Input.

[N] P0.21

Power Supplies

VCC

External supply for the module. 2.8V - 3.6V
