I develop boards end to end for the consultancy's clients: IoT and telemetry, instrumentation, motor control, RF and medical devices. Schematics, multilayer PCBs of up to 18 layers, part selection and BOM, and bring-up support. Most of the freelance projects on this site come from that work.
Braulio Roque Hernández · Embedded hardware & PCB design — About
I'm Braulio Roque, a mechatronics engineering student at Universidad Panamericana. I specialize in embedded hardware, power electronics and high-density routing. While my main focus is electronic design, I keep the whole product in view: from mechanical modeling and firmware to lab validation and bring-up.

Teams & activities
2024 – 2026 Build UP
Designed the control and power PCB for a dynamic earthquake simulator (up to 10 Hz): overcurrent and reverse-polarity protection, a dual power architecture (mains or USB power bank) and a wireless link for real-time remote control during demonstrations.
2024 – 2025 Stella Ignis
Led a rocket's telemetry and avionics system: accelerometer, barometer and GPS acquisition at 200 Hz, altitude estimation with ±3 m accuracy and a real-time bidirectional RF link at 2 km.
2022 – 2026 Pantera Robotics
Developed the control electronics and mechatronic integration for competition robots (Robomatrix Oaxaca 2022): power stages for high-torque traction, sensor conditioning for fast response and tuning of autonomous navigation on drones.
Awards
2026Ceneval Award for Outstanding Performance (EGEL exam)
2026Innovation Journey Award, InkLab project
2021Bronze medal, Mexican National Physics Olympiad
Capabilities
Hands-on experience across the different stages of hardware development.
- Architecture & multilayer design
Schematics, part selection, high-density multilayer routing and integration with the enclosure and firmware.
InkLab - Bring-up & lab validation
Bring-up and debugging on real hardware, validating signals and expected behavior with lab instruments (oscilloscope, logic analyzer and signal generator).
SAFE-LOCKPULSO - Redesign & optimization
Continuing existing projects: replacing discontinued or out-of-stock parts, reducing area and cost, and improving performance.
LOGGERPRISMA - Reverse engineering
Analysis of existing boards to document them, diagnose them or reproduce how they work.
LECTOR RFID - Feasibility & BOM
Pre-design assessment: preliminary parts selection, cost estimate, market research and supplier contact.
CANVAS - Modular prototyping
Boards built around off-the-shelf modules to speed up validation and cut costs, avoiding the fragility and interference of breadboard or loose-wire prototypes.
