Remix of the original Reflow hot plate controller board by Curious Scientist based on Arduino Pro Mini in a smaller form factor (80x80mm).

I also added an extra connection for a thermistor on pin A0.

Please note that the BOM doesn't include the Arduino PRO Mini and MAX6675 thermocouple module.

You will have to source those by yourself.

If you like, you can use this project for MAX6675 thermocouple module and source only the probe itself.

THE SOFTWARE SKETCH IS THE CREATION OF >CURIOUS SCIENTIST< AND IS CURRENTLY AVAILABLE ONLY FOR HIS YOUTUBE MEMBERS.

PLEASE DON'T ASK ME FOR SOFTWARE SKETCH. If you like, you can find here the sketch explained line by line. You can copy it from there : https://youtu.be/9xac7aseDws?t=1027
