This is how the controller should look like.

But it’s still a long way to come there. We are still looking at the blank board.

For building the SBL-Micro you should have printed out the building instructions, the layout plan and the list of parts. Mark every part you have placed on the board on the parts list and may be on the layout plan. This is a way to keep the overview. If you do it this way it’s easy to check if no part is missing on the board.

There often the question if an oscilloscope is really necessary to build the controller. The answer is easy. An oscilloscope is not necessary but very helpful if the controller does not work as expected.
It is possible to us a software solution instead. This uses the LineIn plug of the soundcard . I placed a link to such a software on the download page.
 

Hint: The used SMD electrolytic capacitors are Tantal capacitors. The line on the capacitors marks the (+) side.

Please clean the board carefully with alcohol before soldering.
