About the Robosub teensy PCB

Robosub teensy is an open source NXP PCB design by ryos17, published on GitHub. It is a 4-layer board measuring 120 × 64 mm, with 27 components from 27 distinct parts.

Its main chip is the INA300AIDSQT, from the NXP family. Other key parts include the SN74LVC1G97DBVR. By type, the board carries 25 connectors and 2 ICs.

It belongs with the power & battery designs in this gallery.

From the project

Stanford Robosub Electrical Repository

The first hardware generation of the Stanford RoboSub vehicle. This generation is deprecated — the physical sub no longer exists — and the design files are kept here for reference only. New work happens in gen2/ (current platform) and gen3/ (in progress).

The three gen 1 boards live under PCBs/:

- ComputePowerBoard/ — regulated power supply for the compute stack. - PowerDistributionBoard/ — takes battery input and distributes it to the vehicle's power rails. - TeensyBoard/`** — Teensy 4.0 carrier with the audio shield, the main microcontroller board for this generation.

Robosub teensy: common questions

What microcontroller does the Robosub teensy use?

The Robosub teensy is built around the INA300AIDSQT, from the NXP family.

How big is the Robosub teensy PCB?

The Robosub teensy measures 120 × 64 mm, has 4 copper layers and is 1.769872 mm thick.

How many components are on the Robosub teensy?

27 components, from 27 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 Robosub teensy 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 Robosub teensy 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 Robosub teensy 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.
