+### For Jetpack6+
+Similar to method 2, we need to refer to another document (pinmux) and obtain this pin label information. Refer the links below according to the SoM.
+
+- [Jetson Nano](https://developer.nvidia.com/jetson-nano-pinmux)
+- [Jetson Xavier NX](https://developer.nvidia.com/jetson-xavier-nx-pinmux-configuration-template-v106)
+- [Jetson Orin NX/ Nano](https://developer.nvidia.com/downloads/jetson-orin-nx-and-orin-nano-series-pinmux-config-template)
+
+**Step 1:** Download the pinmux document according to the SoM you are using. Here we choose the [Jetson Orin NX/ Nano](https://developer.nvidia.com/downloads/jetson-orin-nx-and-orin-nano-series-pinmux-config-template) document
+
+**Step 2:** Find the GPIO label (under Customer Usage column) corresponding to the Module Pin Name that we got before. For example, for **GPIO12**, it is **GPIO3_PN.01** and here we refer to **PN.01**
+
+<div align="center"><img width={800} src="https://files.seeedstudio.com/wiki/reComputer-GPIO/4.png" /></div>
+
+**Step 3:** Enter the terminal of the Jetson device and execute this command
+
+```bash
+sudo apt update
+sudo apt install gpiod
+
+gpioinfo
+```
+
+**Step 4:** Find the **GPIO number** corresponding to the **GPIO label** that we got before
+
+<div align="center">
+  <img width={800} src="https://files.seeedstudio.com/wiki/reComputer-Jetson/gpio/gpioinfo1.png" />
+  <img width={800} src="https://files.seeedstudio.com/wiki/reComputer-Jetson/gpio/gpioinfo2.png" />
+</div>
+
+In this case, it is **gpiochip0 line85** corresponding to **PN.01** which is also equal to **GPIO12**
+
+**Step 5:** Then we can use the **gpioset** command to configure the working mode of the GPIO.
+
+```bash
+# To set GPIO12 to HIGH
+sudo gpioset --mode=wait gpiochip0 85=1
+# To set GPIO12 to LOW
+sudo gpioset --mode=wait gpiochip0 85=0 
+```
