I'll suggest adding a generic 2-pin connector symbol to serve as the connection point for the Samsung S23 coil pack. This connector would typically be used to interface the coil pack with your board.
Connector Details Assumed:
Type: Generic board-to-cable connector
Pin Count:2 pins
Designator Suggestion:J1
Would you like to use these assumptions for your schematic? If so, you can apply the connector symbol with these attributes to your schematic.
Based on information in the PDS-0024c Open-Q 8250CS SOM HW Datasheet, the carrier board is designed to accept a nominal 12V DC supply. This external 12V input is then internally regulated to provide the various required rail voltages (which typically include rails such as 1.8V, 3.3V, and 5V) for proper operation of the SOM.
For exact details—including voltage ranges, tolerances, and the specific regulated output values—you should refer to the power supply section of the datasheet.
