To be honest, there is a lot of work to be done in order to have a good PCB and achieve its desired functionality :

1. Software program development, hardware schematic design and development. That’s to say, the hardware engineer need to design a complete hardware schematic (including components choosing), and the software engineer completes the software program.

2. After understanding the design requirements, PCB layout is following. Then exporting Gerber to manufacture bare PCB;

3. In the light of engineering production files, purchasing components, soldering, assembling and testing, which is to realize the design functions;

4. Once finished PCB Assembly + Enclosure Packaging, the product will be available for sale on the market.
