6.15 ST morpho connector
The ST morpho connector consists in male pin header footprints CN11 and CN12 (not
soldered by default). They are 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 21 and Table 22 show the pin assignments of each STM32 on the ST morpho
connector.

1. For more details refer to Table 12: Solder bridges.
2. PA7 is used as D11 and connected to CN7 pin14 by default, if JP6 is ON, it is also connected to both
Ethernet PHY as RMII_DV and CN9 pin15. In this case only one function of Ethernet or D11 could be used.
3. PE2 is connected to both CN9 pin14 (SAI_A_MCLK) and CN10 pin 25 (QSPI_BK1_IO2). Only one function
can be used at one time.
4. PB13 is used as I2S_A_CK and connected to CN7 pin 5 by default. If JP7 is ON, it is also connected to the
Ethernet PHY as RMII_TXD1. In this case only one function of the Ethernet or I2S_A must be used.
