The nRF5340 DK (PCA10095)
features an onboard programming and debugging solution.
In addition to radio communication, the System on Chip (SoC) can communicate with a computer through USB and a virtual COM port provided by the interface MCU.
Hardware drawings nRF5340 DK hardware drawings show both sides of the PCA10095.
Block diagram
The nRF5340 DK block diagram shows the connections between the different blocks.
Power supply
The nRF5340 DK has multiple power options.
Operating modes
The nRF5340 DK has various modes of operation.
External memory
The nRF5340 DK has a 64 Mb external flash memory. The memory is a multi-I/O memory supporting both regular SPI and Quad SPI.
Connector interface
Access to the nRF5340 GPIOs is available from connectors P2, P3, P4, P5, P6, and P24.
Buttons and LEDs
The four buttons and four LEDs on the nRF5340 DK are connected to dedicated GPIOs on the nRF5340SoC.
32.768 kHz crystal
The nRF5340SoC can use an optional 32.768 kHz crystal (X2) for higher accuracy and lower average power consumption.
Debug input and trace
The Debug in connector (P18) makes it possible to connect external debuggers for debugging when the interface MCU USB cable is not connected or the DK is in nRF only mode.
Debug output
The nRF5340 DK supports programming and debugging external boards with nRF51 Series , nRF52 Series, or nRF53 SeriesSoCs. To debug an external board with SEGGER J-Link OB IF, connect to the Debug out connector (P19) with a 10-pin cable.
Extra op-amp
The voltage follower for the power supply uses a dual package op-amp.
Solder bridge configuration
The nRF5340 DK has a range of solder bridges for enabling or disabling functionality on the DK. Changes to these are not needed for normal use of the DK.
