== Introduction ==<br />
<br />
<br />
This is a 27-channel PWM shield that adds 27 independent PWM servo channels to Arduino or pcDuino.<br />

<br />
== Caution ==<br />
<br />
There is a jumper labeled P1 on the shield. If the jumper P1 is installed, the Vin of Arduino/pcDuino will be connected to the external power supply Vin+ of the PWM shield. So please remove the jumper P1 when use it on pcDuino, as the Vin of pcDuino cannot exceed 5V.<br />
