Notes and Changes:

Changes V4 to V5 Per ECR E1400164 and T1400223:
R10 & R15 from 10k to 2.2k
R5 & R23 from 3.9k to 2.0k

These changes were by a desire for more actuation dynamic range.

The bill of materials has been updated to reflect these part value changes, but the actual part numbers is not known. The parts are all 1206 surface mount resistors, and hopefully thin film components were used.
