Extension connectors (CN7 and CN10)

The extension connectors are two 2x20 2.54‑pitch male pin headers (CN7 and CN10). They can be used to
connect the STM32U083C-DK Discovery kit to an expansion or prototype/wrapping board placed on top of it. All
signals and power pins of the STM32 are available on the extension connectors. An oscilloscope, a logic
analyzer, or a voltmeter can also probe this connector.
Table 15 describes the CN7 and CN10 connector pinout.
