It&rsquo;s the free replacement for the old Test_Link and Landrex tools, and it lives open next to my microscope.</p> <p>Its best trick is cross-probing: click a designator on the board and the schematic PDF jumps to that part. Click a part in the schematic and it lights up on the board. Once you&rsquo;ve worked that way, going back to scrolling a PDF by hand feels like doing arithmetic on paper.</p>
