I just got my DragonBoard 410C and the Audio Mezzanine SEEED (both from Arrow). The 410C has the soldering space for the J7 analog exp. The mezzanine has a P4 2x8 female mating connector at the underside of the board.
Do I need to solder a male connector to the 410C before I can use the mezzanine?
Or can I use the P4 connector to attach the needed audio devices?
Thanks for the support.
