Figure 10: nRF52 DK connectors
Some of the signals are also available on connectors
P7
,
P8
,
P9
,
P10
,
P11
, and
P12
, located on the back
side of the
. By mounting pin lists on the connector footprints, the nRF52 DK can be used as a shield for
3.3 V Arduino motherboards or other boards that follow the Arduino standard.
For easy access to GPIO, power, and ground, the signals can also be found on the through-hole connectors
P13
–
P17
.
Note:
Some pins have default settings:
•
P0.00
and
P0.01
are used for the 32.768 kHz crystal and are not available on the connectors.
See
on page 17 for more information.
•
P0.05
,
P0.06
,
P0.07
, and
P0.08
are used by the
connected to the interface MCU. See
on page 6 for more information.
•
P0.09
and
P0.10
are by default used by NFC1 and NFC2. See
on page
20 for more information.
•
P0.13
–
P0.20
are by default connected to the buttons and LEDs. See
14 for more information.
When the nRF52 DK is used as a shield together with an Arduino standard motherboard, the Arduino
signals are routed as shown in the following figure.
