Well I’ve started to run out of power and already needed to add 12v 3 amp external power for modules accessories etc, leaving me with needing 3 wall warts (1 amp pi , plus 2 amp track power /arduino) and no use of my iPad for filming videos, taking pictures, etc to run even a single module. so I decided to just replace my entire micro DCC++ and RPi JMRI set up with ESU 50310 cab control with WiFi throttle and 7 amp booster. For $323 shipped for the whole system, vs $200-300 for a wifi throttle only or umpteen gazillion for a booster, it just makes sense. Plus I have a bunch of their ServoPilot v2.0 accessories so they will integrate easily to the station now. And as small as it is I bet I can set it down the spine of the TTRAK modules... or even just underneath a module. Even better, I can still use the throttle itself up at New Mexico Nscalers when COVID is over.
