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)
