The following tables show the pin connections used in this application. Table 2-1 shows the pin connections
needed to control movement of the CNC machine on the x-axis while Table 2-2 shows the pin connections used to
control movement on the y-axis. Table
2-3 shows the pin connections used for serial communication using the UART
module.
