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 |
| Common interfaces are connected via |
Jumpers |
0Ω resistors |
Jumpers are much easier to use, need no soldering |
| Morpho headers mark |
Most |
None |
Now you can check the PCB mark instead of datasheet |
| DC input |
Yes |
None |
A convenience |
| ST-LINK/V2 |
Separated |
Integrated |
ST-LINK/V2 can be used anywhere else |
| USB fuse |
Yes (500mA) |
None |
The computer USB interface might be harmed without fuse |
| 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. |
| UART indicator |
Yes |
None |
Data communication is visible now |
| 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 |
| Comes with USB cable |
