What's the input voltage range for a Wemos D1 board?
I have a battery pack of 4 AA batteries. This makes 4*1.5V = 6V, but I think they can drop as low as 4*1.2V = 4.8V. Can I hook the battery pack directly to the input voltage socket? Or is this to much?
What happens when I connect the D1 to the USB to program it? Must I disconnect the battery pack first? Sometimes it would be handy to let the USB cable connected to se debug output on the serial monitor.
I'm aware of Power Wemos D1 mini from battery but that only answers whether 3 batteries are enough.
