Hardware architecture

The X-NUCLEO-SRC1M1
The expansion board must be plugged on the matching pins of the development board CN7 and CN10 ST
morpho connectors.
Two hardware configurations are possible depending on the STM32 UCPD peripheral:
• if the STM32 embeds a UCDP peripheral, connect JP2 and JP3 jumpers to CC1_UCPD and CC2_UCPD,
respectively;
