Electronics Engineer and Firmware Development

Hi, I’m Elizzy, an electronics engineer with a strong interest in turning circuit ideas into practical, well-organized PCB projects. My work covers schematics, PCB layout, component placement, routing...
About this Gig

Need a clean, powerful, low noise audio amplifier board? I design class D amplifier PCBs with Bluetooth audio, from schematic to production ready Gerber files.


WHAT YOU GET

  • Class D amplifier circuit design (mono, stereo, 2.1, BTL)
  • Bluetooth 5.x audio integration (A2DP, aptX, ESP32 or QCC modules)
  • Low noise layout: star grounding, proper return paths, EMI and filter design
  • Power supply and battery design, with protection and USB-C charging
  • Complete deliverables: schematic, PCB layout, Gerber, BOM, pick and place
  • Design review, simulation and a DFM check for manufacturers like JLCPCB and PCBWay


TOOLS: Altium, KiCad, Eagle


IDEAL FOR: Bluetooth speakers, soundbars, car audio, guitar and hi-fi amplifiers, smart speakers, portable audio products and startup prototypes.


WHY ME: Clear communication, fast turnaround, and designs made for real manufacturing, not just on paper. Send me your power, channel count and size, and I'll recommend the best amplifier IC and architecture.
