ST STM32U083C-DK - Extension Connectors (CN7 and CN10); Table 15. Pin Assignment for the STM32 on the Extension Connectors

7.2 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.
