Hi, I can design your double-layer PCB for the ESP32-based low-power radio/NFC device, including schematic, PCB layout, Gerbers, BOM, antenna guidance, and a battery-life power budget. The best solution is to first review the enclosure size, battery type, NFC read distance, speaker/audio requirement, wake-up flow, and sleep-current target. Then I’ll design the ESP32 module circuit, NFC wake-on-field interface, low-quiescent power stage, audio amplifier, external button connector, and proper WiFi/NFC antenna placement for a plastic enclosure. I’m comfortable with KiCad/Altium PCB design, ESP32 hardware, NFC reader integration, low-power battery circuits, SMD and through-hole layouts, audio amplifier circuits, antenna keep-outs, BOM optimization, Gerber generation, and prototype-ready documentation. Deliverables will include: * Complete schematic * Double-layer PCB layout * Gerber and drill files * BOM with part numbers * Power budget for 6-month target * NFC antenna placement notes * WiFi antenna placement guidance * SMD/through-hole component support * Manufacturing-ready files I’ll focus on low idle current, reliable wake-up behavior, clean routing, enclosure fit, and a practical PCB package ready for prototype fabrication. Best regards Ankit

@Hmdlawal

HI, KINDLY READ THROUGH MY PROPOSAL Your power budget is the critical part of this design, not the PCB itself. I would first validate the sleep current of every subsystem, especially the NFC wake circuit, regulator quiescent current, and ESP32 power domains, because they determine whether the 6-month battery target is realistic. I have 6 years of PCB design experience and can design a compact 2-layer board in KiCad or Altium, optimizing component placement for reliable NFC reading through the plastic front panel while keeping the WiFi antenna isolated from noisy circuitry. I'll recommend the most practical low-power, cost-effective, and readily available components, then provide the schematic, PCB, Gerbers, BOM, and a detailed power budget to justify the battery-life estimate. One question: what battery chemistry and capacity are you planning to use, and what is the expected number of NFC scans and WiFi connections per day? Best regards, H. Lawal

@VictoriaZ54

I enjoy designing low-power IoT hardware where every microamp matters as much as the PCB layout. I can design your 2-layer PCB, schematic, and manufacturing package around the ESP32, NFC wake-on-field detection, audio playback, and WiFi while targeting a 6-month battery life. I'll recommend components based on availability, cost, and quiescent current, paying close attention to RF layout, NFC antenna placement behind the plastic enclosure, and power-domain switching. Portfolio: [add link]. My plan: Select low-power components and build the schematic with a detailed power budget. Design the 2-layer PCB with proper RF, NFC, and audio separation. Optimize sleep current using load switches and efficient regulators. Verify antenna placement, enclosure constraints, and DRC/ERC. Deliver schematic, PCB, Gerbers, BOM, and power calculations. The biggest risk is standby current exceeding the battery target. I control this by measuring every always-on path, minimizing leakage, and validating the complete power budget before release.

The design will focus on the 6-month battery target by optimizing power paths, selecting low-quiescent-current components, reviewing sleep current consumption, and preparing a detailed power budget. I will also consider NFC antenna positioning through the plastic enclosure and WiFi RF placement to maintain reliable communication. Deliverables will include editable design files, Gerbers, BOM with manufacturer part numbers, schematic documentation, PCB layout, and power analysis report. To begin, I would need the expected battery type/capacity, WAV playback duration and frequency, WiFi usage pattern, NFC module preference, speaker specifications, and enclosure constraints.
