1.2 Introduction to Interfaces on Pedestal

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

• A. The corresponding interfaces of functional interface group 1 and functional interface group 4 are consistent, and the definitions of each interface are shown in Table 2.1.1.2-1:

• B. The corresponding interfaces of functional interface group 1 and functional interface group 4 are consistent, and the definitions of each interface are shown in Table 2.1.1.2-2:

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 2.1.1.2-5, and the LED will light up.

• C. DC Interface of power: use a DC power socket with an outer diameter of 6.5mm and an inner diameter of 2.0mm. The 8.4V 5A DC power adapter provided by the manufacturer can be used to power myCobot 280.

• D. Grove interface: The definition of Grove interface is shown in Figure 2.1.1.2-7, Figure 2.1.1.2-8, and Figure 2.1.1.2-9.

• E. Type C Interface: It can be used to connect and communicate with the PC. At the time that this interface is used, the G1 and G3 interfaces are occupied.

• F. Reset Button: It is used to reset the main control system.

• G. Button A, Button B and Button C: It is used with the screen.

• H. Basic display: It is used with a 2-inch IPS screen for displaying the communication status and calibrating the robot in cooperation with the button.

2.2 Introduction to Terminal Interface

• A. The definitions of each interface of functional interface group 5 are shown in Table 2.1.1.2-3:

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 2.1.1.2-12, and the LED will light up.
