<p>Raspberry Pi output node. Can be used in Digital, PWM or Servo modes.
<p>Digital mode expects a <code>msg.payload</code> with either a 0 or 1 (or true or false),

<p>The initial value of the pin at deploy time can also be set to 0 or 1.</p>
<p>When using PWM mode - expects an input value of a number 0 - 100. It can be floating point.</p>
<p>PWM mode can be used to drive a servo using input values between 10 and 20 only.
