Compare	XNUCLEO	NUCLEO	Remarks
Arduino compatibility	UNO, Leonardo	UNO	XNUCLEO can be configured by jumper to compatible with UNO (default) or Leonardo
Arduino ICSP interface	Yes	None	ICSP is required by certain kinds of shields
USB connectivity	Yes	None	The USB connector of NUCLEO is for debugging ONLY, not available for USB connection
USB connector	Micro USB	Mini USB	Micro USB is the advanced USB standard
Morpho headers mark	Most	None	Now you can check the PCB mark instead of datasheet
Common interfaces are connected via	Jumpers	0Ω resistors	Jumpers are much easier to use, need no soldering
UART debugging	Available while in-circuit debugging	Not available while in-circuit debugging	The NUCLEO integrated ST-LINK/V2 functional chip can be simulated as serial port, however, it's not available while in-circuit debugging, whereas XNUCLEO features a stand-alone USB TO UART chip.
8MHz crystal	Yes	None	Timer is more accurate when using external 8MHz crystal
32.768KHz crystal	Yes	None	Required for RTC
USB fuse	Yes (500mA)	None	The computer USB interface might be harmed without fuse
LEDs	4	1	The more LEDs, the easier to monitor program running status
UART indicator	Yes	None	Data communication is visible now
DC input	Yes	None	A convenience
Button position	Close to PCB edge	Close to Arduino connector	The button won't be untouchable when connecting with an Arduino shield if it were close to the PCB edge
ST-LINK	Separated	Integrated	ST-LINK can be used anywhere else
Comes with USB cable	Yes	None
