Is there any way to recover from suspend mode on jetson nano without using the mouse or keyboard?
For example, apply a defined voltage to a specific pin header.
I followed the instructions on this sites to enable suspend on the Jetson Nano.

Hello @UchiyKei
Awaking The Device
The system can be awakened from deep sleep by common wake sources available on Jetson platforms:
| Wake Source |
Usage |
| Power button |
Press and release the power button on the Jetson device. If the power button is not available, connect then disconnect the power button pin and ground. |
| RTC alarm |
Before entering low power state, program the RTC alarm with the command: $ sudo bash -c "echo date ‘+%s’ -d ‘+ 10 seconds’ > /sys/class/rtc/rtc0/wakealarm" |
| Micro USB cable hotplug |
Connect or disconnect a micro-USB cable to the USB micro-B port for flashing the device. |
| USB remote wakeup |
Press any key on a USB keyboard connected to the device. Note that Linux does not support a USB mouse as a wake source. |
| Wake on LAN |
On another machine on the same LAN, enter: $ sudo etherwake -i <interface> <MAC_address_of_target> |
| SD card detection |
Insert or remove SD card. |
