Does anyone have a photo showing how they have their gateway Moteino connected/positioned on their RPi? I've been using it via the USB port but now need to switch to GPIO. i want everything to look neat and was just looking for an idea. i may consider a MightyHat at some point. thanks
oops. The MightHat includes the Moteino, correct?
Yes the MHat has the atmega328p running DualOptiboot, basically the same as Moteino, but with a bunch more circuitry to support other features.
To just hook up your Moteino to the GPIO to act as a gateway, power it from the Pi 5V->VIN, GND->GND, TX->RX, RX->TX. You would of course program it independently from your PC in advance with the PiGateway sketch. To program it from the PI it's a bit more complex.
