ST morpho connectors (CN7 and CN10)

The ST morpho connectors are two 2.54 mm pitch male pin headers (CN7 and CN10). They can be used to
connect the STM32 Nucleo-64 board to an expansion or a prototype/wrapping board placed on top of it. All
signals and power pins of the STM32 are available on the two ST morpho connectors. A logic analyzer or a
voltmeter can also probe this connector.
Table 12 describes the CN7 and CN10 connector pinout.

1. PA13 and PA14 are shared with SWD signals connected to STLINK-V2EC, it is not recommended to use them as I/O pins.
2. Refer to Section 6.5 for details.
3. Refer to Section 6.10 for details.
4. The ADC input range is 0 <= VIN <= VREF.
