Double-Layer PCB Design for Radio

@MuhammadUzair16

Hi, I am an embedded systems engineer with over 16 years of experience taking consumer products from concept through PCB design, firmware support, prototyping, and production. This project is a strong fit for my low-power ESP32 and mixed-signal hardware experience. I will select practical, sourceable parts, develop the schematic and two-layer layout, and carefully position the NFC and WiFi antennas for the plastic enclosure. The power architecture will prioritize ESP32 deep sleep, a genuinely low-current NFC wake method, efficient regulation, and shutdown of the audio path when idle. I will provide fabrication-ready Gerbers, a complete BOM, and a documented power budget covering sleep, wake, NFC, WiFi, and WAV playback. What battery chemistry/capacity and expected number of daily activations with average playback duration should I use for the six-month calculation? I would be happy to discuss the enclosure and operating profile before finalizing the component choices.

I can design a compact 2-layer PCB for your ESP32-based battery-powered IoT device with long battery life as the primary objective. The design will include an ESP32 module, low-power NFC reader with wake-on-field detection, audio amplifier for WAV playback, efficient battery power management, Wi-Fi antenna, and GPIO connector for an external button. Component selection will prioritize low quiescent current, cost, and availability while ensuring both the NFC and button can wake the ESP32 from deep sleep. I’ll optimize antenna placement for reliable NFC operation through the plastic enclosure and provide Wi-Fi layout recommendations. Deliverables include the schematic, PCB layout, Gerber files, BOM with manufacturer part numbers, assembly files, and a detailed power budget demonstrating the 6-month battery-life target.

I have designed IoT hardware with deep-sleep currents below 10µA, integrated NFC, BLE/WiFi, audio, battery charging, and power management solutions, delivering production-ready schematics, PCB files, BOMs, and manufacturing packages. Approach: ✅ I will design the schematic with ESP32, NFC wake circuit, audio amplifier, battery power system, and low-power regulation. ✅ I will create a compact 2-layer PCB layout with proper antenna placement, grounding, and enclosure size considerations. ✅ I will optimize power consumption and prepare BOM, Gerbers, and a power budget to verify the 6-month battery target. ✅ I will review the design for component availability and reliable manufacturing. Questions: ✅ I would like to confirm the target battery type and capacity constraints, as this is critical for validating the 6-month runtime requirement. ✅ Is the WAV playback duration, speaker power level, and expected daily activation frequency defined for accurate energy calculations? ✅ Do you already have preferred NFC reader modules/components, or should I select the lowest-power option with wake-on-field capability? Best, Yaroslav

⭐⭐⭐⭐⭐ Your project is much more than a PCB layout—it's a low-power IoT design where every microamp matters. The 6-month battery life goal will depend on careful component selection, power management, and PCB layout from the start. With 15+ years of experience in PCB and embedded hardware design, I can develop a compact, production-ready 2-layer PCB around the ESP32, optimized for ultra-low standby current, reliable NFC wake-up, and robust WiFi performance. Deliverables: • Complete schematic and PCB layout • Gerbers and manufacturing files • BOM with cost-effective, readily available components • Power budget validating the 6-month battery target • Recommendations for NFC antenna and WiFi antenna placement within your enclosure I'll also optimize regulator selection, sleep current, decoupling, RF layout, and speaker circuitry to maximize efficiency while keeping the design easy to manufacture. A few questions: Do you have a preferred ESP32 module? What battery type and capacity are you planning to use? Is audio stored locally or streamed over WiFi? I'd be happy to help turn this into a reliable, low-power product ready for prototyping and production.
