After searching for “How to setup Power and Reset buttons for Jetson Orin Nano development board?” I found few articles in this forum giving them as reference:
However the reference Jetson document in them is missing and clear explanation is missing on the button setup, hence this guide
I recently bought NVidia Jetson Orin Nano board for development and a metal case. The case came with 4 pin Metal push button with LED light( Momentary non-latching switch) in it. However it took me long time to figure out the button setup. The above document did guide me however not fully.
You should always rely on the developer board specification to be accurate:
Looking into this you can easily figure out few things:
- You need to use the Button Headers ( J14 in the Board specification )
- To let power button work you need to keep pin 5 and 6 connected always ( use jumper short circuit cap connector)
- The power button’s power cables must be connected to Pin 11 and Pin 12 ( any of the cables can connect to any of the pin )
- The LED lights (-) and (+) should be matched to Pin 1 and Pin 2 respectively
Similarly for Reset button to work
You must connect the button’s cables to Pin 7 and Pin 8 ( any cable to any Pin )
Once connected you are all set
