    I like… but I do wish that the only two external interrupt pins were not used up by the relays. Those Pins 2 and 3 would be nice to available for the external header pins. PCint pin interrupts of course, they work.
    My other wish, is that pin 0 and 1 were still available, like on the uno. My application does not need the usb, software serial is an option, but really don’t want to go that route.
    Good documentation, love the unit, the SD and RTC onboard with relays is just too cool. All in all, it may be a bit on the pricey side.
