I recently bought a gimbal with an 8 bit v2.4 AlexMos controller. It was working alright to start with a weird twitch as the only problem. As I was playing with it, the buzzer suddenly turned on to a constant squeal, the green light went out and the red light stayed on and solid. At the time it was connected to the GUI. I powered off immediately but every time i try to power up again nothing happens but the solid red light and constant squeal from the buzzer. I'm powering with a 12v supply from a 3s LiPo, the motors are two Turnigy 2206.
