Hello,
Attached you can find an extract from the user manual of the STM32L4 MCU. It says: "In case VIN, +5 V or +3V3 is used to power the STM32 Nucleo-32 board, this power source must comply with the standard EN-60950-1: 2006+A11/2009, and must be Safety Extra Low Voltage (SELV) with limited power capability."
What does exactly that mean? Is that so strict? I was thinking of using this little board which supplies 5V for my project: http://www.meanwell.com/webapp/product/search.aspx?prod=MFM-30
