This design is an evolution of the Revision A Boost Controller Board, and going forward will be re-branded as the Wave Energy Controller Board, as the Generator housing now has its controller directly on the power electonics PCBs as well.
2019-08-21 15:13 Wrapped up a the first pass at changes
2: changed power supplies to LT uModules
4: changed differential VSIG to 5V primary, reduce number of channels
1: implement variant for ref 3V0 and 3V3
3: implement variant for RS485
3: added chokes and TVS to CAN
3: set slope control on CANBUS
5: implemented variant for battery monitoring
5: generic renaming on channels
6: need to better define the DIO and review PWM channels
7: added i2c device page
2019-08-26 15:00 REV 2.0.3
1: Removed option for 3v3 ref
1: Cleaned up off page connector names
2: Removed 5V supply as an option (TODO, remove components after approval)
3: Created daughterboard interface header, changed TVS to pushpull single packages
4: Optimized channels for higher resolution in 0-2V input channels that are not employed in the generator can, which is also the range for the battery voltages in the heave cone, and will be the range for the battery box as well as we upgrade all V/I sensing. Also, this greatly reduces part count.
5: Now that 3V0 ref is the standard, all signal reduction is tuned for 3V0 output.
6: Switched RB3-5 triple output drive to a proper opto drive circuit for the ultramotion. Also switched selector resistors to solderblobs.
7: Moved i2c connector into the daughtercard header on page 3 with SPI lines.
2019-09-12 11:12:28 REV 2.1.0
4: Changed R26 value for 3V3 to 3V0 scaling
2: Added more #4 hole for all corners, only one hooked up to chassis.

Post initial layout review, changed to jumper resistors on analog channels for less voltage drop risk.
