1. An irrigation control circuit board, comprising:

  • a microprocessor;

    a plurality of output terminals configured for providing an output current to an irrigation valve in order to actuate the irrigation valve;

    a voltage boosting circuit, including;

    a DC-DC converter; and

    an output current boost capacitor;

    wherein the voltage boosting circuit boosts the output current to an actuating voltage, the actuating voltage being sufficient to actuate an irrigation valve and the actuating voltage being supplied to an irrigation valve driver;

    a power mitigation circuit configured to limit current spikes to the voltage boosting circuit; and

    at least one shunt monitor configured to monitor the output current as it is transferred between the irrigation valve driver and the plurality of output terminals.
