Hi Felix -

Ordered three of the MightyBoosts & three MoteinoUSB w/RFM69HW. I have a 4400mAh battery connected to the MightyBoost, 2.4Amp USB power for input.

Just put the first one together, programmed the Moteino with your sample sketch and started to play with it to bring up the radio to let me know when power has been lost, but as soon as I upload the sketch, the MightyBoost shuts down immediately and powers off the Pi just as fast.

Just want to check and make sure this is the correct behavior when programming the moteino.

Thanks!

Hey Felix -

Didn't see a reply to this - just wanted to make sure that on the MightyBoost that the expected behavior is that the MightyBoost powers off the Pi anytime you program it.

Thanks

Felix

That's expected. The power is kept on by the Moteino, as long as the sketch is running. If you program (resets during FTDI programming) it, it will reset all the pins and hence the HIGH output that keeps power on drops and power is cutoff. That "problem" does not exist on the mightyhat which has a latched output.
