  • ① Power DC interface

Base interface description

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;

  • ① Function interface group 6
  • ② Grove
  • ③ Type C

Terminal interface description

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

  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 pull current of a single tube angle decreases with the increase of the number of pins, 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.
