GPS Tracker V3 - new hardware

This weekend I milled two plates out of alloy to put it onto the NEMA 17 stepper motor with a 1:26 gear head as sold by Phidgets Inc. This combination is quite nice and allows for very precise movement combined with the TMC222 controller I use and actually I would be quite happy with it but the gear backlash is about 2°. No problem and could be compensated by the software easily but again not the perfect solution. Anyway, I'll stick to that for now.

Base plate to hold the electronics

The base plate has got some pockets to mount the electronics, the top plate fits the Manfrotto Quick Release basis 577 perfectly.
