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
Designed my first keyboard :3
It is based on a STM32f042, Kailh Choc switches and features a Type-C jack. It is super smol with a size of just 214x84x17mm, and yes the key caps are hand drawn!
