Front and rear camera(s) bar! Nintendo combined all three cameras into a single bar and cable.

The front camera is watching your every move, in an effort to serve you the best possible 3D with the least possible jitter.

The dual rear-facing cameras track AR cards, and take photos with apparently improved low-light capture.

Sadly, there isn't much component information here. There are no tell-tale inscriptions on either camera board or cables, aside from a vague QR code label that reads "3600 4C11 03YG."
