26 Pin Interface Pin Description

1) Please refer to the figure below for the order of the 26 pin interface pins on the Orange Pi 5 development board



2) The functions of the 26 pin interface pins on the Orange Pi 5 development board are shown in the table below
a. The following is the complete pin diagram of 26pin



b. The table below is the picture of the left half of the complete table above, so you can see it clearly



c. The table below is the picture of the right half of the complete table above, so you can see it clearly

The pwm in the above table has marked the base address of the corresponding register, which is useful when checking which pwmchip in /sys/class/pwm/ corresponds to which pwm pin in the 26pin header.

3) There are a total of 17 GPIO ports in the 26pin interface, and the voltage of all GPIO ports is 3.3v
