EC Shield PCB
The EC Shield allows you to easily start monitoring conductivity levels of any solution. With a hookup for an EC probe (DIY probe can be used with great accuracy) and a hookup for a 1Wire temperature sensor (temperature compensation) it will be great with your next project.

PWM Shield PCB
The PWM Shield allows you to easily add extra PWM outputs to your Arduino. Each shield has 32 PWM outputs, but you can daisy chain these shields together and get up to 640 outputs! Since they can be externally powered you're not constrained by the amount of power an Arduino can provide either.
