I used this module with a microbit microprocessor to quickly test the analog input value and see that I was able to get a temperature reading (as pictured). No issues with the easy setup. The module has a pin header pre-soldered, but it looks as though too much heat was applied (notice the smoky looking "dust" pattern on the pcb board in the second photo). Functional but questionable manufacturing.

Super easy to set up w/ arduino: just 5 wires (two of those for 5v power). I used one of the example sketches from the Adafruit M6675 library - it just worked.The probe is quite well built - there's a metal mesh sheath over all but the last 15cm or so of wire. The wire has heavy duty thermal insulation on it - like the stuff you find in hair drier heating circuits. The mesh sheath is swaged into hard metal sleeve within which resides the actual thermocouple.I heated the sensor end up with a hot air rework tool to just past 300C. The chart shows it as it's cooling back down to room temperature.To get a sense for what kind of latency there's going to be, I touched the sensor end with my fingers for about 5 secs. It took ~~10s for it to start showing in the graph, and then over a minute to cool back down again. Meaning: the probe end does have some mass, so you'll see a delay as it hunts for its new "normal".
