1.2 Introduction to Bottom Electrical Interfaces

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

• A. Table 2.1.5.2-1 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 2.1.5.2-3, and the LED will light up.

1. In the case of using other functions, the IO function is unavailable, and the other function table of the function interface is shown in Figure 2.1.5.2-4.

Figure 2.1.5.2-4

• B. Power DC interface: The myCobot280 is powered by a 6.5mm OD, 2.0mm OD, and a manufacturer's 12V 5A DC power adapter.

• C. Switch: Red means switch,also means powering on, while O means powering off.

• D. USB2.0 interface. Serial port with the standard of main line for 2.0 interface. The USB port is used to copy program files and connect peripherals such as mouse and keyboard.

• E. USB3.0 port (blue) : The port that uses serial bus 3.0 for data connection. The USB port is used to copy program files and connect peripherals such as mouse and keyboard.

• G. HDMI port: The HDMI D-type port connects with the monitor. HDMI port 2 has a priority, and HDMI port is recommended.

• H. Type-C port: connecting to the PC.

• I. SD card slot: The SD card can be inserted and removed. The size of the SD card is 32mm x 24mm x 2.1mm

2 Electrical Interface of the End

2.2 Terminal Electrical Ports

• A. The definitions of each interface of functional interface group 2 are shown in Table 2.1.5.2-2:

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 2.1.5.2-9, and the LED will light up.
