You can just get Xecuter SX OS if you own a USB-C and jig, no need for Xecuter SX Pro if you don't mind installing from a PC, android or whatever you have.
I contacted Team-Xecuter to see if you need the Xecuter SX Pro to use Xecuter SX OS and the said.
Finally! First important question answered! A few hundred to go!
So. We can use SX OS with our jigs and devices. Now people can stop spreading misinformation!
