✅Okay, I got what you want exactly. I am a Senior Embedded Hardware & PCB Design Engineer with over 10 years of experience, providing ESP32-based hardware design, audio circuit design, power management, and production-ready PCB layouts. In my opinion, the key to this project is a clean, low-noise audio path combined with stable power architecture, especially on a battery-powered ESP32-C3 platform. I would focus on proper amplifier selection, grounding strategy, and layer stack-up to ensure reliable voice playback without EMI or distortion. This project is very similar to my previous works. I’ve designed an ESP32-based consumer device with a Class-D audio amplifier, 4–8Ω speaker output, Li-ion charging (BQ series), and BLE control, taking it from schematic to a 4-layer PCB and pilot production of 300+ units. ✅ So, I will divide your project like following: ⚡ System architecture review and component selection ⚡ Schematic design with audio, power, BLE, LEDs, and buttons ⚡ PCB layout (2–4 layers) with EMI/ESD and DFM considerations ⚡ Design review, manufacturing handoff, and iteration support Via private chatting or meeting, I will provide the creative idea and solid technical solution for your project, and I’d like to discuss the budget and timeline in detail. Best regards, Yaroslav
