Arduino Nano RP2040 Connect¶

Hardware¶

Platform Raspberry Pi RP2040: RP2040 is a low-cost, high-performance microcontroller device with a large on-chip memory, symmetric dual-core processor complex, and rich peripheral.

Configuration¶

Please use nanorp2040connect ID for board option in “platformio.ini” (Project Configuration File):

[env:nanorp2040connect]
platform = raspberrypi
board = nanorp2040connect

You can override default Arduino Nano RP2040 Connect settings per build environment using board_*** option, where *** is a JSON object path from board manifest nanorp2040connect.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:nanorp2040connect]
platform = raspberrypi
board = nanorp2040connect

; change microcontroller
board_build.mcu = rp2040

; change MCU frequency
board_build.f_cpu = 133000000L

Uploading¶

Arduino Nano RP2040 Connect supports the following uploading protocols:

• cmsis-dap

• jlink

• picotool

• raspberrypi-swd

Default protocol is picotool

You can change upload protocol using upload_protocol option:

[env:nanorp2040connect]
platform = raspberrypi
board = nanorp2040connect

upload_protocol = picotool

Debugging¶

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

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

Arduino Nano RP2040 Connect does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.
