Re: ANNOUNCING: navX MXP Robotics Navigation Sensor
Joe Hershberger of National Instruments has indicated that the USB ports on the Roborio are powered by a separate regulator with boost capability. The Roborio USB port remains powered all the way down to ~4 volts of VIN from the robot battery.
This is welcome news, as it means that to provide uninterrupted power to the NavX MXP even under brownout conditions, a standard unmodified USB cable connecting the NavX MXP to the Roborio is sufficient. In other words, it is not required to connect the NavX MXP USB port to the VRM in order to provide this backup power source.
