Description
This is an STM32 port of the DerSpatz V1.1 reflow hot plate design. It has some additional hardware & software features and designed to mostly use basic parts for minimal cost. Can directly be ordered and assembled from JLCPCB.
See [Github Repository](https://github.com/Berkays/ReflowPlate) for complete firmware, 3D enclosing models and GUI application.
### Features
- NTC Support with either RT Table curve or steinhart approximation.
- Rotary encoder as main input.
- Wide OLED display support thanks to U8G2.
- Automatic and Manual modes.
- Thermal runaway check in auto mode.
- Profile selection and graphing.
- Dynamic pwm current adjustment for current limiting.
- Automated CubeMx import script.
- Easy configuration and extension.
- Preheating and fan cooling.
