# PCB Board design questions [closed]

I want to design a PCB board computer that is very similar to a raspberry pi or an Orange Pi. It needs to have no ports aside from Ethernet. It should plug directly into an electrical outlet and have have another electrical outlet on the other side of it that can works just like a normal port outlet. On the board I want to have a switch that cuts off the power to the other power outlet but the computer is still powered.

Would this be expensive to manufacture?

Would it be expensive to hire someone to design it for me?

sorry if this may be off topic, but if you could point me in a direction where I can learn more please do :)

• Why do you need a full computer instead of a microcontroller? – Ignacio Vazquez-Abrams Nov 29 '16 at 6:46
• What do you consider "expensive" ? I often find this to be true: if you have to ask what it costs then probably you cannot afford it. Why not use an Rpi or Opi and only make an additional board with the mains switching and the Ethernet stuff (assuming that would even be needed). – Bimpelrekkie Nov 29 '16 at 6:51
• $1500 is less than two days. I don't think that is enough time to do the job. Not if you need full schematic and layout. I am ignoring "bulk" because I doubt you could sell more than 100 of these. So the$30 also probably cannot be realized. If you can sell 100,000 units, then you can maybe get a bulk price. Injection molded plastic tooling is also way more expensive than you probably think. Even a small part will have thousands of dollars of tooling cost. And you will need a lot of compliance tests to be done. I think there is much more NRE than you expect. – mkeith Nov 29 '16 at 6:58
• Do you have a working prototype already ? It will be a lot easier and less risky (saving money) to go to a custom design if you already have working hardware. I'm thinking an Rpi or Opi board with an additional PCB with the special hardware you need. – Bimpelrekkie Nov 29 '16 at 6:58
• @mkeith "$1500 is less than two days" That amount varies a lot, depending on the country the consultant/designer is in. I, for example, living in Eastern Europe, would be willing to work for two weeks for that money. On the other hand, I agree that$30 per unit is not a realistic goal. – m.Alin Nov 29 '16 at 8:46
