Stanford Robosub Electrical Repository

The third hardware generation, currently being designed. The proposed system architecture is shown below; the boards under PCBs/ are the work toward it. The current working vehicle is still gen2/.

- MicroBreakout/ — the main breakout board for gen 3, the successor to the gen 2 MLU breakout. References the shared parts library in ../../importedparts. - BatteryBoards/ — the gen 3 power-management / battery boards, the follow-on to the gen 2 PowerManagement boards (which had heat problems). Two design variants: - PowerManagementV3diode/ — the diode-based design; this is the lead design. -…

Power Distribution: common questions

How big is the Power Distribution PCB?

The Power Distribution measures 151.4 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Power Distribution?

82 components, from 24 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Power Distribution design files?

From the ryos17/robosub-ee repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Power Distribution design in my own project?

The repository has no license, so all rights stay with ryos17. Use it as a reference, and ask the author before reusing the design.
