Hi The GPSTM (and similar) have at least one other “fatal flaw” compared to the TBolt - You can not tune the filter (control loop) parameters. That locks you in to the “big hump” Trimble ADEV that their default settings create.
If I was stuck on a solar battery stack, I think I’d prefer the GPSTM’s wide range switcher over the linear regulators that are needed to make a TBolt run nicely :) There is always the possibility that another “wave” of TBolts might show up. I doubt they will drop back to the $120 range again. It looks like something around 2X to 3X that is now the going rate. Who knows …..
