(Master)
15 DO Master I2C Clock Line
[N] P0.28
GPIO_23 16 DIO General purpose I/O pin. [N] P0.23
GPIO_13 17 DIO General purpose I/O pin. [N] P0.13
UART_RX 18 DI UART_RX [N] P0.11
READY 19 DO
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 20 DO
UART_TX, This is also the ADC function of the
nRF52
[N] P0.05
GPIO_1 21 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 22 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 23 DIO General purpose I/O pin. [N] P0.15
GPIO_8 25 DIO General purpose I/O pin. [N] P0.08
SPIS_MISO 26 DI
Configured as a SPI slave this pin is the SPI
data output. Refer to Datasheet for more details
[1].
[N] P0.07
SPIS_MOSI 27 DO
Configured as a SPI slave this pin is the SPI
data input. Refer to Datasheet for more details
[1].
[N] P0.06
SPIS_CLK 28 DI
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 29 DI
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 30 DO
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 31 DO
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 32 DI
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 33 DI Reset pin. Active Low Input. [N] P0.21
Power Supplies
VCC 12 P External supply for the module. 2.8V - 3.6V
