Participate in schematic design of embedded mixed-signal circuits (OrCAD), integrating power supplies, microcontrollers, lighting and display drivers, memory (FLASH/EEPROM), regulators, batteries, high/low-speed interfaces (USB, UART, SPI, I²C), RF transceivers, sensors, and analog/digital components. Bring up, characterize, and debug systems and circuits using lab tools (oscilloscopes, multimeters, logic analyzers, power supplies, hi-pot testers, etc.).
