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. Figure 1-4, Figure 1-5, Figure 1-6, and Figure 1-7 are the signal names of the four expansion interface groups on the front of the base, which are used to connect different Arduino development boards.

Expansion interface group 1 and expansion interface group 4 can be used to expand development board with interface as same as Arduino UNO, such as Arduino UNO, Arduino MEGA 2560, etc;

Expansion interface group 2 and expansion interface group 3 can be used to extend the development board, whose pin is consistent with Arduino MKR WiFi 1010 interface.

B. Figure 1-8 shows the signal of the expansion interface group 5 on the pedestal. This part of the interface corresponds to each functional interface of the connected Arduino development board.

C. Power DC interface It uses DC power socket, with an outer diameter of 6.5mm and an inner diameter of 2.0 mm. Users can use the 8.4V 5A DC power adapter provided by the manufacturer to mycobot 280 for power supply.

2 Electrical Interface of the End

2.1 Introduction to the End of Robotic Arm

A. The schematic diagram of the side interface of the end is shown in Figure 2-1 and Figure 2-2 :
