Simple board to create an inverted
second motor driver to run the X1 and
Y1 motors when running MPCNC with
GRBL. Use two of these instead of
E0 and E1 driver positions.

<b>R/C MASTER-SMD! - v1.14 (03/30/2013)</b><p>
<p>This library is a collection of SMD ONLY resistors and capacitors by various manufacturers. The pad sizes, spacing and silkscreen widths have been tweaked for use in dense fine pitch layouts where space, alignment and precision are critical. In general these components are designed for routing in grid increments of 5 mils</p>
<p>* Silkscreen line elements are a minimum of 8 mils in width. All components have text sizes of 0.032" or 0.04".</p>
<p>* A silkscreen text values use a ratio of 18 in all cases.</p>
<p>* ALL PADS AND PART OUTLINES ARE SNAPPED TO A 5 MIL GRID!</p>
<p>* See ULP script <b>migrate-rc-master.ulp</b> to auto-migrate parts from <b>rcl.lbr</b></h4>.</p>
<p><h4>All components are prefixed using the following conventions:</h4></p><br>

As a general guideline, SMD resistors are typically rated as follows:<p>
0402 = 1/16 watt<br>
0603 = 1/10 watt<br>
0805 = 1/8 watt<br>
1206 = 1/4 watt<br>
2010 = 1/2 watt<br>
2512 = 1 watt<br><p>
