Sobre mim
I design PCBs and embedded firmware for practical hardware prototypes. Using Altium Designer, KiCad, and EasyEDA, I create schematics, PCB layouts, and manufacturing files, including Gerbers, drill files, BOMs, and assembly outputs. I develop STM32 firmware in C/C++ for sensor integration, motor control, and communication. My projects include an STM32G4 BLDC reaction wheel controller, an STM32F405 micromouse with encoder and IMU feedback, and a battery-powered NFC logger PCB. Share your requirements and target deliverables, and I can help plan the design and handoff.... Saiba mais

Designed and revised Altium controller PCBs for a satellite BLDC reaction wheel at StarLabs, NUS. Integrated motor drive, sensor feedback, and communications; prepared boards for fabrication and assembly. Simulated the control system in Simulink and developed field-oriented control and sensor-interfacing firmware for the attitude-control prototype.

Designed a compact STM32F405 control PCB for the open-source OBO Mouse v4 micromouse, reducing board size by more than 40% versus the prior revision. Integrated motor drivers, encoder inputs, an IMU, and infrared sensors. Implemented and tuned PID motion control using encoder and gyro feedback; the robot reached 3 m/s.
