Another idea : can you add a couple of ESP GPIO with a pullup and a dual pin header to ground, so we can use jumper to switch SW into specific mode (for exemple, mining on a pool or with a local node RPC connection,... we will discuss these mode later when designing the SW), and a couple of LED on ESP to have status from SW also.
Ooo, yes. blinkylights are always good.
I had imagined all of the configuration to happen through a webpage hosted on the ESP32, or via bluetooth. That's what the "Admin Task" is all about. But, I agree especially during this R&D phase having some buttons/jumpers UI will be useful. I'll add a couple.
