<![CDATA[How to address serial on ATOM Matrix]]>I have looked around a bit on the website, but I have questions about using serial on the ATOM Matrix. How many serial ports are available? What pins correspond the port(s)? Is the USB C overlapping the serial port? Thanks!

You can use the USB-C port as a serial monitor (for debug or Micropython REPL).

There is also a Grove port that can be used for I2C, I/O, or UART. Also there are multiple GPIO ports on the bottom: G19, G21, G22, G23, G25, G33
