General Specification |
Arduino compatibility |
XNUCLEO can be configured by jumper to compatible with UNO (default) or Leonardo |
Arduino ICSP interface |
ICSP is required by certain kinds of shields |
USB connectivity |
The USB connector of NUCLEO is for debugging ONLY, not available for USB connection |
USB connector |
Micro USB is the advanced USB standard |
Morpho headers mark |
Now you can check the PCB mark instead of datasheet |
Common interfaces are connected via |
Jumpers are much easier to use, need no soldering |
UART 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 |
Timer is more accurate when using external 8MHz crystal |
32.768KHz crystal |
Required for RTC |
USB fuse |
The computer USB interface might be harmed without fuse |
LEDs |
The more LEDs, the easier to monitor program running status |
UART indicator |
Data communication is visible now |
DC input |
A convenience |
Button position |
The button won't be untouchable when connecting with an Arduino shield if it were close to the PCB edge |
ST-LINK |
ST-LINK can be used anywhere else |
Shipment Weight |
0.210 kg |
Shipment Dimensions |
14 × 14 × 4.5 cm |
