Hello guys, I'm just wondering if the rockpro 64 can take analog output, I'm thinking to use a current sensor to measure something, but I didn't see the pi-2 bus can take an analog output like this. The sensor is like  ACS712 30A.

Any idea? Thanks

There is no ADC/DAC on RockPro64.

How hard could it be to add the ADC of your choosing?

Well, thats really confusing question!
I don't know anything about these devices (RockPro.). But don't you have discreet digital inputs in GPIO?  If so, just attach your favorite ADC, and away you go.
