With a flick of the spudger, the remaining antenna connectors come free—releasing what we theorize to be a miniature Stargate. That, or the omnidirectional antenna array.
Each of the six PCBs is a pair of antennas. The smaller boards are 5 GHz, and the larger are 2.4 GHz, alternating around so that each antenna pair is 120° offset from the other two pairs of the same frequency.
Some engineer was probably pretty excited to design antennas in an arrow shape. Looking snazzy!
That one extra-long cable runs a bit lower on the motherboard, where it connects next to a ZigBee network co-processor—hello 802.15.4 (coming soon).
