More than 4 current sensors

Hello all,

I’m making a new board based on emonTx. I would like to know if there is any hardware or software limitation to have 7 current sensors. ADC 0 to measure the AC/AC voltage and the other ADC pins to measure the current sensors.

If I would like to have more current sensors maybe I have to move to Atmega 1280, no? Did someone experience this kind of problem before?

Best regards,


You will find at least one design if you search the old forums.
