- Comes with a separated ST-LINK/V2 module
Advantages
| 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 |
