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. -…

Micro Breakout: common questions

What microcontroller does the Micro Breakout use?

The Micro Breakout is built around the BSC0702LSATMA1, from the NXP family.

How big is the Micro Breakout?

The Micro Breakout measures 123.5 × 83 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Micro Breakout?

48 components, from 39 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 Micro Breakout 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 Micro Breakout 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.

Can I test firmware for the Micro Breakout without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
