Fabrication procedure and cost

The price of the fabrication will highly depend of the number of boards and the companies you decide to use both as PCB manufacturers and the component suppliers. Here are two nice articles explaining how to approach the problem choosing the PCB manufacturer form and component supplier from But in most of cases it will always boil down to the price :)

PCB fabrication + Self assembly - preferred choice 📢

This is probably the proffered choice for making this board in lower quantities. You can order the PCBs from your manufacturer, buy the components from your supplier of choice and solder the boards yourself. The board has been designed to be relatively easy to solder.

PCB fabrication

Download the gerber files and provide them to your PCB manufacturer of choice. So far I have used seeedstrudio and JLCPCB. The price of 10 PCBs is around 5$ but the shipping was around 20$.


On top of these prices you will have to pay shipping of approximately 20€.

Component purchase

Here is a complete list of all the components you will need to make the board:

The same list ( a bit optimized for PCB manufacturers ) you can download on link Bill of Materials. In my case I have used Mouser as my component supplier but the components of this board should be easy to find with any other supplier. The price of the components was around 10$ per board and the shipping was again around 20$ (for orders under 50$).


The components with the manufacturers numbers I have chosen are not really set in stone, feel free to optimize them both in terms of prices and values if necessary.

Board assembly and soldering

Once when you have all the components and the PCBs the fun begins. All the components are relatively easy to solder. All the capacitors are 1206, all the resistors are 1210, the connectors are all through-hole and there is no real small SMD components. Therefore with some patience and you should have no problems soldering this board with a regular soldering iron and a bit of time. Therefore take a coffee and one deep breath and you are ready for 20 minutes of fun.


The board itself already has the descriptor names of the components on it so it should be easy to determine which component goes where. There is also an assembly drawing in the Pick and Place folder of the gerber files if you prefer to have a printed version.

PCB fabrication and assembly service

This option is a lot simpler and produces much better results. It is also even cheaper for larger quantities > 50pcs. To order the boards, download the Gerber files and Bill of Materials and supply it to your manufacturer of choice. In my case, I’m using the JLCPCB.
