ST morpho connector
The ST morpho connector consists in male pin header footprints CN11 and CN12 (not
soldered by default). They can be used to connect the STM32 Nucleo-144 board to an
extension board or a prototype/wrapping board placed on top of the STM32 Nucleo-144
board. All signals and power pins of the STM32 are available on the ST morpho connector.
This connector can also be probed by an oscilloscope, logical analyzer or voltmeter.
Table 12 shows the pin assignments for the STM32 on the ST morpho connector.

1. To be compatible with the previous versions of the ARDUINO® Uno V3 board, A4/A5 do not support I2C.
2. I2S_B group has the same port as SAI_B group, but they have a different pin map.
3. VREF+ is not connected to CN7 by default.
4. QSPI signals (PA2, PB10, PE15, PB0, PE12 and PE14) are shared with timer signals on CN10.
5. PB11 is not available on ‘-P’ suffixed boards.
