About the Robosub Power PCB

Robosub Power is an open source PCB design by ryos17, published on GitHub. It is a 2-layer board measuring 120 × 60 mm, with 45 components from 23 distinct parts.

Other key parts include the INA300AIDSQT, SN74LVC1G97DBVR, AUIR3241STR, BSC0702LSATMA1 and NVTR01P02LT1G. By type, the board carries 11 connectors, 11 resistors, 8 ICs, 6 capacitors, 3 diodes and 2 jumpers.

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.
