My Mobile APRS (MoPi No Longer Dead)

Michael WA7SKG

In case anyone is interested in this project, here is my mobile APRS headend so far. Almost ready for final installation in the truck.

The front view is as I will see it from the driver's seat. The little white pushbutton at the top is to turn the RPi on and off via the MoPi board. (Black button use is TBD.) The little wireless keyboard is for occasional data entry and will normally be stored.

The rear views show the arrangement of the boards. On the bottom is the Raspberry Pi 3B+. On top of that is the TNC-Pi. Topping it off is the MoPi 2 power board. There is the 12V cable that goes down to the power distribution block with PowerPoles. The multi-colored jumpers provide power from the GPIO pins to the 7" touchscreen. The short jumper to the pushbutton is the start-up/shut-down switch. Kind of kludgy for now. I hope to neaten it up some later.

The case is a SmartiPi Touch. The base shown in the pictures was just for use on the bench. The VESA mount shown to the left of the Pi stack mounts the whole works in the truck. Finally, how it will look in the truck. This picture was taken in the middle of the Phase III upgrade before the rest of the equipment was installed.

I hope you find this interesting.
