N2+

Hardware

Platform ST STM32: The STM32 family of 32-bit Flash MCUs based on the ARM Cortex-M processor is designed to offer new degrees of freedom to MCU users. It offers a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation, while maintaining full integration and ease of development.

Microcontroller	STM32F405RGT6
Frequency	168MHz
Flash	1MB
RAM	128KB
Vendor	Netduino

Configuration

Please use netduino2plus ID for board option in “platformio.ini” (Project Configuration File):

[env:netduino2plus]
platform = ststm32
board = netduino2plus

You can override default N2+ settings per build environment using board_*** option, where *** is a JSON object path from board manifest netduino2plus.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:netduino2plus]
platform = ststm32
board = netduino2plus

; change microcontroller
board_build.mcu = stm32f405rgt6

; change MCU frequency
board_build.f_cpu = 168000000L

Uploading

N2+ supports the following uploading protocols:

• dfu

• jlink

• stlink

Default protocol is dfu

You can change upload protocol using upload_protocol option:

[env:netduino2plus]
platform = ststm32
board = netduino2plus

upload_protocol = dfu

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).

N2+ 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.

Compatible Tools	On-board	Default
J-LINK
