Hi everyone 

Can someone give me schematic of EC Meter 2.0 circuit (DFR0300)? Are 2.0 and 1.0 versions much different? thank you everyone.

The V2.0 schematic is not open source.

The schematic of the two versions are not very different, the biggest difference is that V2.0 can be powered by a wide voltage. So V2.0 adds a voltage regulator circuit.
