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. -…

To order: common questions
What microcontroller does the To order use?
The To order is built around the TEENSY4.1, from the NXP family.
How big is the To order PCB?
The To order measures 151.4 × 80 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the To order?
111 components, from 54 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 To order 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 To order 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 To order 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.
