THE PROCESS OF CREATING A NEW DEVICE
First there is the idea, then the concept, assumptions, feasibility study, block diagram, functional diagram and if necessary, the selection of a microcontroller, simulation, library of components with 3D views, determination of the device size - 3D model, PCB design, full production documentation: Gerber + NC Drill, Pick & Place, paste and glue templates, material list - BOM, assembly instructions - 2D and 3D view and commissioning instructions, if there is a microcontroller, then work on embedded software begins: program structure, configuration, drivers for peripherals, test program, main program, tests, programming manual and testing instructions for the entire device.
