 What is this? Hey, there's a lot of stuff going on my desk right now. First up I've got this mcp 23017 breakout and I got my tester PCB I have a new thing now where when I order my PCBs from Peace JLC PCB I get the prototype for the panel and I also get the tester PCB at the same time So that way I put it together and then I just put some code that it's really fast But it actually tests like every pen and GPIO and the I squared C address and it Beaps when it tests and then I'm also checking out some samples of pink PCB So we got our first batch of pink PCBs from PCB way, but our Standard PCB house can also make pink PCBs. So they sent us some pan tone Pantone chip like samples. These are actually PCB, but with the color So going forward we'll have two possible suppliers for these beautiful pink PCBs.
