@alvaro Great article. (finally came around to read it ;) ) It took me a moment to parse what they did from the PCB photo. Maybe you can add a schematic of the JLink abomination to the article? ;) ... that said, it is a decent idea to optimize BOM lines using 10k resistors. If you already have 1% 10k resistors in the BOM and you have board space, this might be a decent optimization to do.
