XIOA B2B connector

I’m interested in using the XIOA ESP32-S3 in a limited run product ( with the round display). It will require a daughter board so would like to use the B2B connector to connect the daughter board to three ESP. Is there documentation on the pin out and mating connector

Thanks

Les

The Schematic which you can find on the Official Github Page has all the Pinouts listed:

The Connector is the DF40C-30DP-0.4V(51).

You can also check out it´s Datasheet here:

I hope this helps,
