V2 is still in definition.
1. A buzzer will be added, config in GUI
2. A status LED RGB will be added to front, config in GUI. Tricolor fade= sleep, Red fade = reflowing, yellow fade = cooldown, green fade = ready to use. (Good for loud manufacturing floors where buzzer will not be heard)
3. I plan to have a high current low side driver FET for a fan control input. My plan is for this to be a DC fan, not an AC Fan/Relay input, config in GUI
4. GPIO & UART interface for extended application, config in GUI
These are niche features I don't expect the majority of users to use. I don't want to add too many of such features in fears of over complicating a controller that is meant to be simple and easy to use. Let me know if there any features you are dying to have in rev 2 and I will certainly consider them.
