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
