Can you tell me more?
If I have one Unity running normally with on/off switch, then this one you’re selling driven by canbus.
I would just add the Loop Key that I could pull/insert to use as the on/off for the 2nd Unity?
My unity is perfectly fine😂, and I’m asking $220 shipped, buy so I don’t end up making another build. No shade to Steph but when you short anything on a pcb, it most likely means something else will come up later on. $220.00 for a OG unity is a killer deal and you won’t encounter the newer unity QC problems
Switching the low side while you have CANBUS or any other low voltage ports connected will essentially put high voltage on those ports. And I don’t think I’d want to put -51V on a CANBUS wire, might not end well. But I haven’t tried it.
As long as you switch the red it should be fine, although just spinning the wheels will be enough to boot up the second ESC, and that will probably make this not work in 2WD mode. But at least not work in such a way where as you’re not destroying something.
