Yes, I downloaded it from that website some days ago.
I was connecting the Unity to my adjustable power supply, and I tried too with the battery, it didn’t work anyway. I was trying too, holding the power on switch and the blue led went on until I release the switch.
I’m looking for Flipsky VESC, because I haven’t been able to eskate for a month… 
Thank you for the response, I love the forum!
