HW-111 Pre-Charge Rev 4 + Motor Interface Rev 3 (#73) ...

* ELEC-364 Changed optoisolator, IN+ to one of the AND inputs instead of IN-, connected LATCH_OUT to inverter, changed R7 and R9 to 1208 resistors, added mosFET switching circuit between LATCH_OUT and optoisolator, removed mosFET switching circuit between AND gate and RS Latch

* HW-111 Precharge Rev 4.0
- Changed HV directives to use a mask instead
- Removed 4 way crosses from the schematic
- Changed opto-isolator to low side switching and removed the P-FET

TODO
- Update library from master
- Change comprarator to TLV1701
- Look into removing S-R latch
- Redo layout to include motor interface (controller board + MCP2515)
- Look into adding thermistors to the pre-charge and discharge
resistors?

* HW-111 Pre-Charge Rev 4
- Updated libraries from master

* HW-111 Motor Interface Rev 4
- Modified pre-charge circuit to remove an inverter
- Added fuse holder
- Changed to a hierchael design for readablitiy
- Combined most of motor interface and pre-charge

TODO:
- Review schematic and fix designators

Library changes
+ FUSE 3A 250VAC/450VDC RADIAL
+ FUSE HOLDER PC-TRON RADIAL
+ IC OPTOISOLATOR HCPL-0211 8-SOIC

* HW-111 Motor Controller Interface/Pre-Charge Rev 4
- Fixed net naming on the controller board interface
- Reannotated schematic

* HW-111
- Connected ISO_GND between schematic sheets
- Fixed footprint links for Blue LED, Diode 60V 3A, and 3POS ULTRA-FIT

* HW-111 Motor Controller Interface/Pre-Charge Rev 4
- Changed LED on ISO_12V to blue

* HW-111
- Finished preliminary layout for isolated section

TODO
- Review placement
- Finish placement for LV section
- Consider adding a common mode choke + filtering caps to CAN
- Fix PESD1CAN footprint

* HW-111
- Fixed footprint for PESD1CAN TVS diode
- Began routing. Have 18/84 nets remaining

* ELEC-364 Pre-charge rev 4
- Continued routing

* HW-111
- Finished preliminary routing for PCB

TODO
- Add test points to PCB
- Add labels in silkscreen for connectors, LED, HV symbol etc
- Layout review

* HW-111 Pre-Charge Rev 4
- Finished layout, no DRCs

Library
- Added DIODE TVS 160V to schematic and footprint libraries

* Generated gerbers, still have to generate the BOM and PDFs

* ELEC-364 Pre-Charge Rev 4 + Motor Interface
- Updated FUSE HOLDER PCS to include supplier part number and parameters
- Updated BOM

* Updated libraries from master
