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 188.8.131.52-4, Figure 184.108.40.206-5, Figure 220.127.116.11-6, and Figure 18.104.22.168-7 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.

2.2 Introduction to Terminal Interface
- A. The definitions of each interface of functional interface group 6 are shown in Table 220.127.116.11-1:
I: input only.
I/O: This function signal includes input and output combination.
When the single tube corner is set as the output terminal, it will output 3.3V voltage.
The source current of a single tube angle decreases with the increase of the number of pins, from about 40mA to 29mA.
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 18.104.22.168-11, and the LED will light up.
B. Type C interface: It can be used to communicate with PC and update firmware.
C. Grove interface: The definition of Grove interface is shown in Figure 22.214.171.124-12
