Changes from V1 Chip PCB (v3b_2025)
- Pin bindings changed according to pin bindings .csv and WaferSpace_COB_70pins/V3_COB_Original, COB mounting footprint replaced chip socket a. Added Bus 1-5 pins, routed out through 2x3 header pin Breakout b. Removed NPAIR_4_BODY, PPAIR_4_BODY, ISINK_32 pins c. Changed trace width from standard .25 to .15
Further design considerations and questions
- LDO - Already have voltage supply protection, is there any reason of convenience to keep LDO for 2.5V or other voltage
- Power Net Switch - Is it desireable to have an aditional low drop mechanical switch for power net for chip safety
- Feedback from V1 board - Are there any issues with original V1 design that need to be addressed

Questions
How big is the V3 Motherboard PCB?
It measures 135.3 × 55.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the V3 Motherboard use?
64 parts, built around the UM6K34NTCN. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the V3 Motherboard KiCad files?
From the SWTORboi/MV3C_PCB_TEMP repository on GitHub, at the commit this page was made from: the board is V3_Motherboard/V3_Motherboard.kicad_pcb and its schematic V3_Motherboard/V3_Motherboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the V3 Motherboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask SWTORboi before reusing the design.
