Nordic nRF5340 DK
Nordic's dual-core Bluetooth LE development kit with Arduino-compatible headers, current measurement support, and Segger debugger.
Processor
Nordic nRF5340 dual-core Arm Cortex-M33
Logic
3.3 V GPIO
Power
USB, coin cell, external supply
Format
DK with Arduino headers
Check before wiring
- Some GPIOs are shared with LEDs, buttons, debugger, and external memory.
- 3.3 V IO only.
- Network/application core ownership affects firmware access to peripherals.

Simplified technical illustration. Pin data is source-backed; verify against the linked documentation before wiring.
Hover, tap, or focus a pad to inspect a pin. Use arrow keys to move between pins.
- nRF5340 application-core GPIO is 3.3 V and not 5 V tolerant; on-board I2C pins need external pull-ups.
- Digital functions can be re-routed in firmware; A0-A5 map to fixed AIN-capable pins on P0.
- P0.xx/P1.xx aliases are nRF5340 app-core ports per the Nordic PCA10095 / Zephyr board map.
