1.2 Introduction to Interfaces on Pedestal

Notice: Functional interface group is Dupont interface of 2.54mm, and 2.54mm Dupont wire can be used externally.

• A. Table 2.1.7.2-1 shows the definition of each interface of the functional interface group 1.

Notice:

1. I/O: This function signal includes input and output combination.

2. When the single tube corner is set as the output terminal, it will output 3.3V voltage.

3. The source current of a single tube angle decreases with the increase of the number of pins, from about 40mA to 29mA.

4. If a certain GPIO is set to the output mode and outputs a high level signal, the circuit connected to the LED is shown in Figure 2.1.7.2-2, and the LED will light up.

• B. Power DC interface： It is a DC power socket with an outer diameter of 6.5 mm and an inner diameter of 2.0 mm; the 12V 5A DC power adapter provided by the manufacturer can be used to power the mycobot280.

• C. Switch: After pressing it, the internal power turnes on, and the key lights up with a white light; when it is pressed again, the white light turns off, so does the internal power.

• D. Type C interface： It can be used to connect and communicate with the PC.

• E. HDMI interface: This interface is HDMI type A interface. If you want to display the robot operation interface, show the operation page to other equipment terminals by connecting the HDMI display interface.

• F. USB2.0 interface: it is an interface for data connection conforming to the standard of main interface of 2.0; The USB port is used to copy program files and connect peripherals such as mouse and keyboard.

• G. USB3.0 interface: it is an interface for data connection conforming to the standard of main interface of 3.0; The USB port is used to copy program files and connect peripherals such as mouse and keyboard.

2.2 Terminal Electrical Ports

• A. The definitions of each interface of functional interface group 2 are shown in Table 2.1.7.2-2:

Notice:

1. I: input only.

2. I/O: This function signal includes input and output combination.

3. When the single tube corner is set as the output terminal, it will output 3.3V voltage.

4. The source current of a single tube angle decreases with the increase of the number of pins, from about 40mA to 29mA.

5. If a certain GPIO is set to the output mode and outputs a high level signal, the circuit connected to the LED is shown in Figure 2.1.7.2-8, and the LED will light up.
