1.2 Base interface description

Note: The functional interface groups are all 2.54mm DuPont interfaces, and 2.54mm DuPont cables can be used externally;

​ A. Figure 2-6 shows the definition of each interface in functional interface group 1.

​ F. Type C interface: It can be used to connect and communicate with the PC. When this interface is used, the G1 and G3 interfaces are occupied.

​ G. Reset button: used when the main control system is reset.

​ H. Button A, Button B and Button C: Use with the display screen for functional operation.

​ I. Display screen: Use a 2 inch IPS screen, which can be used to display the myCobot communication status / coordinate the button to correct the robot origin and other functions.
