Marine Electronics Design

Built for the
demands of the sea.

Custom marine electronics engineered by Ernesto Trevino-Pena — from precision navigation systems to ruggedized sensor arrays, designed to perform where conditions are most extreme.

What I Build

Full-spectrum marine
electronics engineering

From concept to sea trial — every discipline you need to bring a marine electronics product to life.

Custom PCB Design

Schematic capture through layout and fabrication-ready files. Every board designed for the corrosive, high-vibration marine environment — conformal-coated and salt-spray tested.

Firmware Development

Bare-metal and RTOS embedded software for microcontrollers. Deterministic, power-efficient code built to run reliably in temperature extremes and under electromagnetic interference.

Navigation Systems

GPS/GNSS integration, autopilot controllers, chartplotter interfaces, and AIS transponders. Engineered to IMO and NMEA 2000 standards for professional-grade accuracy.

Environmental Monitoring

Multi-sensor systems for depth, temperature, salinity, heading, and atmospheric data. Real-time logging and alerting for commercial, research, and recreational vessels.

Communication Systems

DSC-capable VHF radio interfaces, satellite modem integration, NMEA networks, and custom bridge communication architectures for single-operator and fleet deployments.

System Integration

Connecting existing onboard electronics into a unified network. NMEA 0183/2000 bridging, CAN bus design, wireless sensor nodes, and vessel IoT dashboards.

About

Where engineering
meets the ocean

I'm Ernesto Trevino-Pena, the engineer behind ETP Electronics. My work sits at the intersection of electronics engineering and the sea — designing systems that mariners can stake their safety on.

Every product I design is built with the marine environment in mind: salt spray, vibration, electromagnetic interference, and power constraints don't get second chances at sea. That means rigorous design practices, thorough testing, and a relentless focus on reliability before anything ships.

  • Hardware design from schematic to manufactured board
  • Embedded C/C++ and Rust firmware development
  • NMEA 0183 & NMEA 2000 protocol expertise
  • IP-rated enclosure and connector specification
  • CE and FCC pre-compliance guidance
  • Prototype testing and sea trial support
