Felix, I've been looking around and I like what you've achieved, and open source too. However I couldn't find the schematics for the mightyhat. Are these published?
I'm planning on using the mightyhat as a mysensors gateway, I've just a few questions.
Does the mightyhat have a serial connection to the RPi? I gather that I can use the RPi to program the mightyhat, can I use the mightyhat to wirelessly program other moteinos?
And perhaps a question for the mysensors forum, but somebody here may know, does mysensors replace the boot loader, or can I use the moteino bootloader to wirelessly reprogram mysensor nodes?
Its such a shame that you don't have a distributor for the U.K, or even one that stocks the products that I need in the eu!
Yes you can wirelessly program a target Moteino with MHat or with any Moteino, or with any Arduino+RFM69.
In fact the only requirements are for the target to run Dualoptiboot and have a FLASH MEM chip.
The mightyhat guide (https://lowpowerlab.com/guide/mightyhat/) is a bit lacking, but there are only a few pins connected to the Pi headers, the rest are pass-through.
The connected ones are:

Fantastic. I can wait to receive my MightyHat!
