ST STM32

Hardware layout and configuration UM1974
36/85 UM1974 Rev 9
6.14 ST Zio connectors
CN7, CN8, CN9 and CN10 are female on top side and male on bottom side connectors.
They include support for ARDUINO
®
Uno V3. Most shields designed for ARDUINO
®
Uno
V3 can fit to the STM32 Nucleo-144 board.
To cope with ARDUINO
®
Uno V3, apply the following modifications:
• SB138 and SB143 must be ON
• SB140/147/150/157/167/171 must be OFF to connect I
2
C on A4 (pin 5) and A5 (pin 6
of CN9).
Caution:1 The I/Os of STM32 microcontroller are 3.3 V compatible instead of 5 V for ARDUINO
®
Uno
V3.
Caution:2 SB12 must be removed before implementing ARDUINO

power being
provided on CN7 pin 6. Refer to Table 12: Solder bridges for details on SB12.
Table 13 to Table 20 show the pin assignment for each STM32 microcontroller on the ST Zio
connectors.
