Having needed a temperature logger several times in the past, after hacking two together for spontaneous testing, I decided to develop a proper one. This is my result. :3

It can record up to four channels with thermocouples or NTCs connected and send them either directly via USB-CDC (as CSV/TSV) or via SCPI. If you use the NTC input, you can map very small input ranges to the full ADC range, I used this as a 4-channel body thermometer (range: 32°C-42°C).

I also did a small oopsie there, all inputs are labeled as „input 3”, so I got the blind redone with proper silkscreen and in pink
