I've connected everything on my steadycam DYS, and I plug it on my computer with USB and alimented with a battery. But I always have the error message in red "sensor is not conected" and I have a lot of I2C error. I've checked all the connection between the yaw and the main board and the IMU and the main board but nothing has changed, the green light on the mainboard is still falshing green and the red one is just on.

Please someone help me ! :(
