   This example shows how to configure the u-blox NEO-F10N GNSS to send NAV SIG reports automatically
   and access the data via a callback. It also demonstrates how to mark the L5 signals as healthy.
 
-  Note: the NEO-F10N only supports UART1. It does not support I2C, SPI or built-in USB.

   To run this example on the SparkFun NEO-F10N breakout, you need to open the USB-TX and USB-RX jumpers
   to isolate the on-board CH340 USB interface chip. See Hardware Connections below.
