    <h3>I2C Connection</h3>
	<p>Configure the connection you want to use to communicate to your I2C device. Native I2C and USB to I2C converters are supported.</p>
	<h3>Interval</h3>
	<p>The interval defines the time between status checks. It is in milliseconds, and the interval starts after the previous check has finished.</p>
	<h3>Chip Selection</h3>
	<p>The range and type of the chip are part of the part number, e.g. "PCA9685-0003-D-B" has a range of "0003" and a type of "D-B"</p>

	<h3>Output Values</h3>
	<p>The output will send an object as the payload keyed by the value, <code>{temperature: 77.234, pressure: 1.54356}</code>.</p>
