I faced the problem and want to clarify the information about Jetson nano developer kit GPIO. As it said in the documentation the output from the Jetson GPIO is 1,8v ( CMOS – 1.8V [ST] from Jetson Nano Data Sheet page 17). However, in that tutorial ( https://www.jetsonhacks.com/2019/06/07/jetson-nano-gpio/ ), it is said that the output is 3.3V.
I want to clarify that information because I can’t switch relay by using Jetson Nano GPIO. I think it is because of the luck of the current.
I want to know exactly what is the output voltage and output current from Jetson Nano GPIO J41.
Also, I have noticed that some GPIO pins output 3.3V but other 1.8V.
Could you provide the information about it, because the info from the documentation is unclear.
Thank you in advance!
