design a PCB as small as possible with a micro controller on it. the PCB should be round and diameter of the PCB should not be more than 5cm. The basic function of the PCB is that there will be a camera attached to the micro-controller which will take images initially for at least a minute, and these images will be stored in an external memory, these images will then be transmitted wireless through an external port. to find a suitable micro-controller , and memory choice with complete analysis is also included in this project, the preferred micro-controller is pic32mx series. all the software used , all the schematics and programming should be presented in a complete document form. power system is also included in it. it might not a single PCB or layers of PCB but then the thickness should not be more than 4cm. its more of a research based project to find out how compact a design can be. so keep in mind both the perspectives i.e. hardware and selection of the components through research. this project is needed to be done as soon as possible.
