Cuttable PCB

An STM32 Nucleo-64-P board is divided into two parts: ST-LINK and target STM32. The
ST-LINK part of the PCB can be cut out to reduce the board size. In this case the remaining
target STM32 part can only be powered by V
CN5, or by V and 3.3 V Arduino connector CN8.
IN
It is still possible to use the ST- LINK part to program the STM32, using wires between the
CN3 and SWD available signals on the ST morpho connector (SWCLK CN5 pin 17, SWDIO
CN5 pin 15 and NRST CN5 pin 14, same I/O level as V

Embedded ST-LINK/V2-1

The ST-LINK/V2-1 programming and debugging tool is integrated on the
STM32 Nucleo-64-P board.
For information about debugging and programming features, refer to ST-LINK/V2 in-circuit
debugger/programmer for STM8 and STM32 User manual (UM1075) at the
website.
The changes versus ST-LINK/V2 version are listed below.
New features supported on ST-LINK/V2-1 are:
•
USB software re-enumeration
•
Virtual COM port interface on USB
•
Mass storage interface on USB
•
USB power management request for more than 100mA power on USB
The following features are no more supported on ST-LINK/V2-1:
•
SWIM interface
•
Application voltage lower than 3 V (need to add level shifter to support it)
