Would appreciate some engineering help…
I’m thinking one of these https://www.makitatools.com/products/details/XTR01Z, with one of these https://www.amazon.com/Mean-Well-NES-350-12-Switching-110-240/dp/B007K2H0GI/ref=sr_1_2?ie=UTF8&qid=1539626357&sr=8-2&keywords=meanwell+power+supply+12v.
The PS is rated 12-18 volts, should work ok with the router. I wonder, is it feasible to use it to power the SO3 as well. I forget, is the SO3 24 volts?
Thanks
