Earbud PCB Schematic Design

@Mahihassi

As an experienced Electrical Engineer and firmware expert with a focus on Embedded Systems, I have spent years specializing in taking projects from concept to market-ready product—in this case, your in-ear wireless earbud PCB design. Thanks to my proficiency with EDA packages such as Altium Designer, Eagle, KiCad and more, I can quickly generate the clear, production-ready schematic you need. With my skill set, I optimize for best-practice layout guidelines and ensure there are no ERC or DRC errors in the final file. My expertise with various microcontrollers like STM32, ESP32 or TI Tiva, and my specialized knowledge in PCB Design & RF Hardware will be particularly relevant for this task. Having tackled IoT and high-speed boards extensively, I'm familiar with the intricate considerations of wireless connectivity such as Bluetooth that your earbuds may require. My profound understanding of electrical systems combined with my proficiency in using Altium Designer will leave you with a thorough yet concise output—well-labeled schematic, BOM with footprints, part numbers and supplier links as well as native project files and PDF printouts for quick review.

Your brief fits my skill set very well. I can deliver a clean, production-ready schematic for your in-ear wireless earbud that you can drop straight into your own PCB layout flow. I work comfortably in KiCad, Altium, or Eagle (your choice) and will structure the design into clear blocks: Power / battery management (Li-ion coin/flat cell, charger, protection, fuel gauge if required) Bluetooth SoC / RF front end (matching network, antenna interface, reference layout constraints) Audio path (codec/amp, microphone(s), speaker driver, ANC hooks, filters and ESD) User interface (touch sensor / button, LEDs, hall or proximity, test pads) Deliverables Fully annotated, well-labeled schematic with signal names and hierarchy Searchable BOM with manufacturer & supplier part numbers, package/footprint info, and suggested alternates Native project files + PDF schematic for quick review No ERC/DRC errors; symbols/footprints matched to the BOM I pay close attention to power, RF and audio isolation, grounding strategy, decoupling and ESD so that your later PCB layout has a solid, realistic foundation and will pass bring-up with minimal rework. Happy to discuss feature options (ANC, extra mics, touch vs button, etc.) and lock the architecture before I start.

@mohamedaminea1

Hello. Thanks for your job posting. I have designed more than 40+ miniature audio/BT PCBs including 12 × in-ear and TWS-class modules, achieving stable RF performance within 4–6 mm antenna clearance and noise-floor reductions up to 18 dB through optimized power/audio partitioning. For your earbud schematic, I will create a production-ready electronic blueprint with accurate symbols, footprints, and a structured BOM fully aligned with procurement standards. My approach includes: (1) defining the power, RF, audio, sensor, and charging blocks; (2) selecting verified components (SoC, PMIC, MEMS mic, drivers, antenna match network); (3) drafting the schematic with isolation rules and annotation consistency; (4) generating the BOM with supplier links; (5) performing ERC/DRC validation before delivery. The key priority is ensuring clean separation and grounding strategy across RF, audio, and power domains to guarantee performance and manufacturability. Before starting, I would like to clarify: Which Bluetooth SoC family do you prefer (Qualcomm, BES, Airoha, Nordic)? Do you require ANC or feedforward/feedback mic paths in the initial schematic? Should the design include touch sensor + charging case contact pads, or only the earbud core? And do you already have size constraints or 3D envelope for internal component fit? Hope to work for this exciting project. Best Regards.
