Figure 2.1.5.2-7 End of the robotic arm
- ① Servo interface
- ② Atom
Figure 2.1.5.2-8 End of the robot arm
- ① Functional interface group 2
- ② Grove
- ③ Type C
4.2 Terminal interface description
- A. The definitions of each interface of functional interface group 2 are shown in the following table:
| Label | Signal name | Type | Function | Remarks |
|---|---|---|---|---|
| 5V | 5V | P | DC 5V | |
| GND | GND | P | GND | |
| 3V3 | 3V3 | P | DC 3.3V | |
| G22 | G22 | I/O | GPIO22 | |
| G19 | G19 | I/O | GPIO19 | |
| G23 | G23 | I/O | GPIO23 | |
| G33 | G33 | I/O | GPIO33 |
Note:
I: Input only.
I/O: This function signal includes input and output combination.
When the tube corner is set as output, it will output voltage 3.3V.
The source current of a single tube corner decreases with the increase of the number of pins, from about 40mA to 29mA.
If a GPIO is set to output mode, it outputs a high level signal, the circuit connection is shown in Figure 2.1.5.2-9, and the LED light will light up.

B. Type C interface: can be used to connect to the PC for communication and update firmware.
C. Grove: defined as shown in Figure 2.1.5.2-10
Figure 2.1.5.2-10 Grove
D. Servo interface: used for the end extension gripper, currently supports the matching adaptive gripper.
E. Atom: used for 5X5 RGB LED (G27) display and button function (G39)
