Welcome! Actually you are watching my JBC soldering station project. Version 1 will be improved at some points however it works fine too. Planned Improvements: Software and application USB-C connector will be used to update the software in DFU mode. USB2.0 HS will be used FREERTOS will be used for task scheduling The software application will be more flexible for migrate to other MCUs StemWin GUI will remain for STM32F4 or higher, 16x2 LCD driver will be used for slower MCUs ... Hardware and PCB PCB will remain the same size AC transformer with triac will remain to avoid SMPS's high frequency noise Opamp will be revised if it is possible it will be changed to a better one Zero crossing detection may be changed to a more simple one Ambient temperature sensor and I2C connection will be removed ... ;)
