Affordable and flexible platform to ease prototyping using a STM32L053R8T6 microcontroller.
Table of Contents
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.

Shared UART on pins D0 and D1
These pins are shared with the PC Serial connection via STLink. If you need to use these pins independently, see this page: https://developer.mbed.org/teams/ST/wiki/Use-of-D0D1-Arduino-pins
These headers give access to all STM32 pins.
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):

This video shows how to get started with ARM mbed Integrated Development Environment using STM32 Nucleo platform:
Nucleo ST-LINK/V2 driver installation and firmware upgrade
For more information, please refer to:
The following section describes known limitations of the platform. Note that general issues are tracked into the mbed repository available on GitHub.
Note: Nucleo-L053R8 platform doesn't support RTOS due to its flash size. Please do not import mbed-rtos library into your project.
