2226025830 Rev.2.0.0 - Rewired for full piezo circuit control 
- Moved ERR_LED to Pin2/PD4; replaced with V_FOL_PWM on Pin1/OC2B to
   adjust Voltage Follower level
 - Moved Z_Min_Trig to Pin9/PD7; replaced with VCOMP_PWM for adjusting
   comparator threshold voltage reference
 - Attached series resistor ladder to gain amp voltage divider,changed
   all resistor values to 470R, allowing a gain of 5 values: 10x, 6.8x,
   5.15x, 4.15x, and 3.47x
 - Repositioned decoupling capacitors to be more in line with the
   schematic

118e8cf7e0 Added v2.0.0 Extruder board, rewire for 60p 
This is a first draft of the new rewiring scheme
Moving from 1mm pitch 26pin to 0.5mm pitch 60pin
for greater number of signals. Should allow for
the new planned features.
