I am looking for a pcb to incorporate low cost mini pinhole digital camera (not cctv), with image storage capability (i.e. sd card) and linked to a pir to trigger the camera, with refresh rate around 3-5 seconds. pir's on ebay, but struggling with the rest. help pls

What i do when designing a circuit:
Design the circuit using arduino ( as lots of tutorials and information is available, also arduino forum is one among the best ).
Burn arduino bootloader in uC, program it through arduino, and finally use it with your external hardware.
This makes the work lot easier. Thanks to Arduino.
A PCB with camera + sd card isn't available yet. You will have to assemble them seperately.
