@NeverDie Yes, you are correct - it is based on ATMega1284P. So not relevant
My point is that I'd rather stick to the datasheet rather than overclock, but that's just me. And yes I realise that Moteino is overclocking, but the size, voltage and flash are really appealing to me.
@TheoL No damage. Water went up about 7 feet on our lake but had another 11 feet to go to threaten our property. Biggest flooding was to the south of us. We did have a fun time hiding out in our laundry room during tornado flying up to the east of us. Also, I do not think the radio is dead - hooked it by accident to my Uno testing board and it was transmitting just fine. Love these things - very tough.
I'm wondering what the minimum input voltage is. The description only says max. 6.5V input voltage from the battery, but does not say what the minimum is. Both the nrf24l01+ as well as the atmega328P work with 3.3V, so if I use three AA batteries, that should be fine, right? I suppose using two AA batteries is not enough?
@YuryPol as far as I know, all licenses require some form of documentation. In all cases I know of, this is documented with the license or on the licenses official site.
