The next stage of the reflow oven project is moving to a custom PCB for the controller electronics. Overall the board is based on the ATmega32u4 with a DS3231 RTC. The LCD module is intended to be driven by one of Adafruit’s Serial backpacks. There is an area of LED indicators (something I learned from a previous project) and some extra VCC/GND pins sprinkled about.
Additionally I am working on a re-work of the enclosure which is based on the dimensions of a Rigol benchtop DMM. I’ll be working on that while I wait for the boards to come back from SeeedStudio.
