Felix,
I recently purchased a couple of MightyBoosts to provide power control and backup for my BrewPi (http://www.brewpi.com/) and another RPi I use.
I have a few questions on the setup:
Looking through all the pages on the MightyBoost and your blog entry about changing over your Pi Gateway, I did not see anything on the code for the RPi or what connections you used for the RPi, so I assume the setup is the same as the ATXRaspi, is this correct? I tried to get the info from the pictures, but there was no picture of the connections for the RPi.
On the MightyBoost page you acknowledge an issue with the BootOK signal from the RPi and a fix. I assume you are referring to pin A7 not D7 since there is no D7 on the MightyBoost pinout. So to correct the issue we need to add a jumper wire between A0 and A7. Also, looking at the sample sketch MightyBoostControl.ino (https://github.com/LowPowerLab/RFM69/tree/master/Examples/MightyBoostControl) it looks like it still references A7. Do we need to make changes to the sketch? or will it work as coded?
Thanks for all your great work!!!!
Dan
Thanks :)
It is actually D7 indeed (A7 is used for battery readings). This is the BootOK signal from Pi. It is not explicitly defined on the silkscreen but it is there in the diagram:

So just solder a jumper wire from D7 to A0.
I have updated the sketch for this: https://github.com/LowPowerLab/RFM69/tree/master/Examples/MightyBoostControl
