Modular printed circuit board assembly and method to operate the same

A method for operating a modular printed circuit board assembly comprises:

• connecting, by a plurality of connectors of a housing unit, a host interface board of a plurality of host interface boards with a plurality of module boards;
• connecting, by the plurality of connectors of the housing unit, a module board of the plurality of module boards with the plurality of host interface boards;
• conducting, by a hear transfer unit of the housing unit, the heat to a heat sink, and wherein a heat sink is a passive heat exchanger for conducting the heat generated by the electronic device;
• and
• reading, by an identification unit of the housing unit, the unique identification of the electronic device from the host interface board to determine a structural combination of the electronic device.

A method for working of a camera working process with respect to a modular printed circuit board assembly comprises:

• directing, the scattered light rays from the target object on an image sensor pixel area by using a lens chosen according to the requirement of a user;
• converting, an equivalent voltage by the analogue-to-digital-converter unit placed in each pixel wall depending upon the intensity of the light;
• digitalizing, the analogue voltage and sent to digital data from an image sensor;
• receiving, the digital by an image co-processor and the image processing is carried out, wherein the processed image is then sent as digital data to a micro-controller;
• converting, the digital data into data packets depending upon its configuration;
• and
• receiving, the data packets by the host interface processor for further image processing activity.
