Hi there,
UNFORTUNATELY NOT!! C’mon seeed Give us SKU# with the B2B connector on the darn thing… Really !
I don’t need or want extra cameras and Sd readers laying around just to get the B2B connector on the Sense version of the S3.
My MORE i/O thread shows the expansion boards users can make and USE if they have the mating connector.
DING DING…
