README
PCBs/sensor_board/README.mdTransmitter Board
This directory contains the PCB designs for the sensor board.
The front of the submarine contains several sensors underwater: a pressure transducer and a thermistor. The pressure transducer is used to measure the pressure of the water. The thermistor is used to measure the temperature of the water. The sensor board reads these sensors and sends the data to the main board through I2C.
Power:
- 3.3V (no voltage regulator onboard - must be clean 3.3V)
Sensors:
- Analog input for external pressure transducer
- 10K Thermistor for water temperature readings
Communication:
- Communicated to the submarine main_board through I2C.
- The board features SWD interface for debugging and is programmed through SWD.
What's done?
- Schematic is finished.
- PCB layout is finished
- 3D models and fabrication outputs are generated
What's to do?
- Ordering and fabrication

Questions
How big is the OceanAI PCB?
It measures 62.8 × 97.5 mm and has 4 copper layers, 4.69 mm thick.
What parts does the OceanAI use?
124 parts, built around the LM324AD, NEO-6M, A4988SETTR-T and ADP1221. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the OceanAI KiCad files?
From the daniel360kim/OceanAI repository on GitHub, at the commit this page was made from: the board is PCBs/main_board/main_board.kicad_pcb and its schematic PCBs/main_board/IMU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OceanAI design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
