And more about lost usb connection here:

Loss of USB connection Autosteer Module

Good morning all, I come to you today because I very often lose the usb connection. I installed a small relay on PWM2 in order to cut the voltage in the Phidgets when the guidance is disabled. I noticed that the loss of USB connection happens when I deactivate the guidance. Here is my current montage: -PCB -BNO055 installed -RTK on -AOG v4.1.12 -I cut the red wire of my USB cable to avoid double powering of the Arduino Thanks in advance for your feedback Have a good day, Thomas
