Is it possible to get access to both UARTs on the Artemis Nano board or is the 1 UART dedicated to the USB connection?

Hi seanmc,

The Artemis Nano has two UART ports you can use. The first is tied to the USB connector through the USB-to-Serial converter. The second, Serial1, is tied to the TX1 and RX1 pins broken out on the board. If you want to use those, just use Serial1.pring/read(); instead of Serial.print/read();. This example from the Apollo3 Arduino Core demonstrates that in more detail.
