MakerX G300 wiring and configuration

I have a new MakerX G300 and have a few questions;

  1. I assume the UART1 port is 3.3v? I have used voltage shifters (5V to 3.3V) previously, but just wanted to confirm.

  2. If controlling the VESC via UART from an MCU, I assume it is UART1 that you need to communicate with?

  3. In APP settings within the VESC tool, you need to set APP to UART and then baudrate in UART to 115200 (what I am using).

Is there any other setting required to control via UART?
