revisions from POT4
- add 5pin, 1.25mm header for strain gague
- removed unused input resistors and capacitors
- On POT4 a 1meg resistor was stacked on CC3 - this resistor added to SCH and PCB
- removed 4th order filter, changed 3way jumper to 2way
- 2nd order filter is now NON-Inverting
- input cable shield can be connected to COM via 0603 resistor
- changed PCB pattern for output driver caps to CAP200-SQ (acurately represents compoent shape)
- changed 0805 output cable CAP to 1206. Panasonic X5R series @ 25V 1uf to 10uF!
- added 10 turn POT for variable gain (optional)
- change CD2 (0.1u in derivative circuit) to 1206 size (was 0805)
