NUCLEO-F031K6

Affordable and flexible platform to ease prototyping using a STM32F031K6T6 microcontroller.

Overview

The STM32 Nucleo board provides an affordable and flexible way for users to try out new ideas and build prototypes with any STM32 microcontroller line, choosing from the various combinations of performance, power consumption and features.

The Arduino™ connectivity support and ST Morpho headers make it easy to expand the functionality of the STM32 Nucleo open development platform with a wide choice of specialized shields.

The STM32 Nucleo board does not require any separate probe as it integrates the ST-LINK/V2-1 debugger/programmer.

Information

Only the labels written in blue/white or green/white (i.e. PA_4, PB_5, A0, D14, LED1...) must be used in your code. The other labels are given as information (alternate-functions, power pins, ...).

You can find more details on the available pins and labels in the following files (link to the latest mbed-dev library version):

Information

By default the PA_5 (A4) and PA_6 (A5) pins can only be used as Input floating (ADC function). Remove SB16 and SB18 solder bridges in order to use these pins as Digital output and have access to other functions (DigitalOut, SPI, PWM, etc...). Refer to the user manual for more details.
