Drawing a wiring diagram

Hi,

I want to show the hardware of my project with wiring diagram including the connections with sensors. I used fritzing for raspberry pi but it is raspberry. Is it possible for nano?

Not sure about this, you can share the schematic for check. And there is a product design guide in DLC for your reference of custom design on nano. https://developer.nvidia.com/embedded/dlc/jetson-nano-product-design-guide
