Good advice here. I haven&#x27;t used KiCad yet, though this thread might finally spur me to try it. I&#x27;ve been using a super simple program called FreePCB for really simple analog stuff that can be routed by hand.<p>The thing that gets sent to the board fab is a set of files in &quot;Gerber&quot; format. So, the Gerbers are your last chance to confirm that the boards will be what you want. I suggest using a Gerber viewing program and look carefully at all of the files to make sure that they agree with your conception of what you expect the board to look like.<p>Finally, whatever fab house you choose, read all of their instructions and design rules, both to confirm that your board has a chance of being made, and because it&#x27;s educational.<p>I&#x27;ve been happy with www.pcbfabrication.com for several runs of boards. I know people who go to a different house for every order, shopping around for the best price, but that just adds one more level of effort and worry for me. So I&#x27;m loyal to a good supplier.
