Project summary

• Design and develop an electronic board for the EyeFish IoT system intended for marine environments. The board will perform multi-sensor data acquisition, embedded digital filtering and processing, and communication with the cloud.
• Ensure energy management, electrical robustness and reliability in marine conditions, followed by prototyping and environmental testing of a functional prototype.

Main objectives & tasks

• Define the electronic architecture of the board and select appropriate microcontrollers and peripherals compatible with the EyeFish system.
• Produce the electronic schematic and develop the PCB (layout and manufacturing files). Integrate analog acquisition circuits for multiple sensors.
• Implement firmware to acquire, filter and process sensor data, handle communications protocols and manage power; test compatibility with EyeFish and perform multi-test verification.

Technical stack & required skills

• Analog & digital electronics design; PCB design using Altium.
• Experience with STM32 microcontrollers and embedded programming in C/C++ or MicroPython.
• Familiarity with communication protocols: UART, I2C, SPI, RS485 and basic IoT fundamentals (cloud communication, data transmission).
• Basic signal processing (embedded digital filtering) and techniques for electrical robustness in marine environments.

Deliverables & testing

• Complete electronic schematic, PCB design files, BOM and assembly notes; documented firmware source code and build instructions.
• Test procedures and reports: environmental testing results, electrical robustness tests, and functional validation with the EyeFish system; presentation of a working prototype.

Intern responsibilities

• Implement analog acquisition circuits, perform PCB layout and collaborate on prototyping and bench tests.
• Develop and validate embedded firmware: drivers for sensors and communications, embedded filtering/processing and power management routines.
• Document schematic, PCB, firmware and test procedures; present the final functional prototype to the team.

Additional expectations

• Perform integration tests with the EyeFish platform and iterate on hardware/software issues discovered during environmental testing.
• Work collaboratively with the team to ensure manufacturability, reliability and compliance with marine deployment constraints.
