Mainboard
This is the largest PCB in the Pyra, with a wide range of different functions. It could be compared to the motherboard in a traditional desktop computer, with the addition of a keyboard and gaming controls on one side. Display-support hardware and the processor itself are each on separate PCBs. There is a space for a WWAN&GPS module. This may be populated with various pin-compatible chips designed for different regions, or not at all, depending on which Pyra model you buy.
Rumble
Haptic feedback is provided through vibration generated by an electric motor with an unbalanced mass on its driveshaft. [1]
