1.2 Description of base interfaces

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

A. Figure 2.1.8.2-4, Figure 2.1.8.2-5, Figure 2.1.8.2-6 and Figure 2.1.8.2-7 are the signal names of the four expansion interface groups on the front of the base. These interfaces are used to connect different Arduino development boards. Function interface group 1 and function interface group 4 can be used to expand development boards with the same pins as Arduino UNO, such as: Arduino UNO, Arduino MEGA 2560, etc.; Function interface group 2 and function interface group 3 can be used to expand development boards with the same pins as Arduino MKR WiFi 1010;

C. Power DC interface: Use a DC power socket with an outer diameter of 6.5mm and an inner diameter of 2.0mm; the 12V 5A DC power adapter provided by the manufacturer can be used to power myCobot 280.

2 Electrical interface of the end of the robot

2.1 Introduction to the end of the robot

• A. The end of the robot is shown in Figure 2.1.8.2-9 and Figure 2.1.8.2-10:

• ① Servo interface

• ② Atom

• ① Functional interface group 6

• ② Grove

• ③ Type C

2.2 End interface description

• A. The definitions of each interface of functional interface group 6 are shown in Table 2.1.8.2-1:

Note:

1. I: Input only.

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

3. When the tube angle is set as the output end, it will output a voltage of 3.3V.

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

5. If a GPIO is set to output mode, it outputs a high-level signal, and the circuit connection is shown in Figure 2.1.8.2-11, and the LED light will light up.

• B. Type C interface: can be used to connect and communicate with the PC and update the firmware.

• C. Grove: Definition as shown in Figure 2.1.8.2-12

Figure 2.1.8.2-12 Grove

• D. Servo interface: used for end extension gripper, currently supports matching adaptive gripper.

• E. Atom: used for 5X5 RGB LED (G27) display and button function (G39)
