User Manual
Remarks
XNUCLEO can be configured by jumper to
compatible with UNO (default) or Leonardo
ICSP is required by certain kinds of shields
The USB connector of NUCLEO is for debugging
ONLY, not available for USB connection
Micro USB is the advanced USB standard
Now you can check the PCB mark instead of
datasheet
Jumpers are much easier to use, need no soldering
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.
Timer is more accurate when using external 8MHz
crystal
Required for RTC
The computer USB interface might be harmed
without fuse
