I want to be able to turn a Jetson Nano devkit on and off remotely using an Arduino. According to the user guide, pins 1 and 2 of J40 will turn on the device when they are shorted together if auto power-on is disabled. However, i want to control it with a microcontroller instead of a button. What would be the best way to go about doing this?
I have a few ideas:
- connect pin 1 of J40 to an arduino IO pin, drive it high by default, and drive it low to connect it to ground and initiate power-on
- connect a transistor or mosfet between pins 1 and 2 and enable it to initiate power-on
- connect a relay between pins 1 and 2 and enable it to initiate power-on
Option 3 would almost certainly work, but I would prefer to use 1 or 2 because they would be cheaper and less complex. Would either of those two ideas work?
