Overview of the PCBOverview of the PCB
PCB is for camera section of device
Small as possible
Independently powered
Two layer board

nRF2401A ConstraintsnRF2401A ConstraintsAlready on its own PCBCustom footprint neededNo ground plane underneathConnection to main PCB through
either headers or soldered directly.

BlueSMiRF ConstraintsBlueSMiRF ConstraintsSimilar to usmirfAlso on it’s own PCBCustom footprint neededPlaced with headers or mounted
on surface with lots of solder

Pixart CameraPixart Camera
Similar to a DIP
Hard to find footprint
Measure dims. using caliper
Custom footprint
7
Powering the BoardPowering the Board
All components require at least
3.3 volts
Battery powered
Haven’t yet decided what battery
will best fit our design (i.e.
alkaline, Li-ion, etc)
