Nordic nRF51X22 Development Kit(PCA1000X)

Hardware

Platform Nordic nRF51: The Nordic nRF51 Series is a family of highly flexible, multi-protocol, system-on-chip (SoC) devices for ultra-low power wireless applications. nRF51 Series devices support a range of protocol stacks including Bluetooth Smart (previously called Bluetooth low energy), ANT and proprietary 2.4GHz protocols such as Gazell.

Microcontroller	NRF51822
Frequency	32MHz
Flash	256KB
RAM	32KB
Vendor	Nordic

Configuration

Please use nrf51_dk ID for board option in “platformio.ini” (Project Configuration File):

[env:nrf51_dk]
platform = nordicnrf51
board = nrf51_dk

You can override default Nordic nRF51X22 Development Kit(PCA1000X) settings per build environment using board_*** option, where *** is a JSON object path from board manifest nrf51_dk.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:nrf51_dk]
platform = nordicnrf51
board = nrf51_dk

; change microcontroller
board_build.mcu = nrf51822

; change MCU frequency
board_build.f_cpu = 32000000L

Uploading

Nordic nRF51X22 Development Kit(PCA1000X) supports the following uploading protocols:

• blackmagic

• cmsis-dap

• jlink

• nrfjprog

• stlink

Default protocol is jlink

You can change upload protocol using upload_protocol option:

[env:nrf51_dk]
platform = nordicnrf51
board = nrf51_dk

upload_protocol = jlink

Debugging

Debugging - “1-click” solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Nordic nRF51X22 Development Kit(PCA1000X) has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
