Overview of the PCBOverview of the PCB
PCB is for camera section of device
Small as possible
Independently powered
Two layer board
3
PIC18 ConstraintsPIC18 ConstraintsNot many constraints28 Pin SOICBy-pass Capacitors

nRF2401A ConstraintsnRF2401A ConstraintsAlready on its own PCBCustom footprint neededNo ground plane underneathConnection to main PCB through
either headers or soldered directly.
5
BlueSMiRF ConstraintsBlueSMiRF ConstraintsSimilar to usmirfAlso on it’s own PCBCustom footprint neededPlaced with headers or mounted
on surface with lots of solder
6
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)
