I bought this with the rest of my meshtastic gear out of fear of having no idea what was going on with my hardware. For a home node I’m not sure I needed it as a USB connection to my laptop and/or Bluetooth to my phone gives me all the info I need. BUT I’m describing an ideal workbench environment where everything happened to work right the first time. Maybe more valuable in a situation where your hardware in the field isn’t working and you need some insight.Just a side note, soldering could be a challenge if you’re old like me and don’t have steady hands due to carpal and cubital tunnel problems. By its very small nature there isn’t a lot of room for error whether you try to mount directly to the board or you try to use the included connector hardware.
