I will design esp32 smart home pcb layout and sensor node hardware
PCB Design ESP32 Arduino KiCad and IoT Hardware
About this Gig
Are you looking to build custom ESP32 smart home hardware, smart switches, or wireless IoT sensor nodes? I specialize in designing reliable ESP32 PCB layouts optimized for Home Assistant, ESPHome, MQTT, and industrial IoT automation.
Whether you need a compact battery-powered environmental sensor node or a high-voltage AC relay control board, I deliver safe, factory-ready circuit boards designed for manufacturing.
What I Offer:
- Custom ESP32 smart home PCB design & schematic layout
- AC/DC relay control circuits (optocoupler isolation & surge protection)
- Environmental sensor integration (BME280, DHT22, mmWave radar, PIR, light)
- Low-power deep sleep optimization for long battery life
- Power supply design (USB-C, Mains AC-DC Buck, LiPo solar charging)
Deliverables You Will Receive:
- Ready-to-order Gerber & NC Drill files (JLCPCB / PCBWay)
- Detailed Circuit Schematic (PDF)
- Bill of Materials (BOM with LCSC part numbers)
- 3D STEP Models for 3D printed enclosures

FAQ
Is this PCB design compatible with Home Assistant and ESPHome?
Yes! I design hardware with full pinout compatibility for ESPHome, Tasmota, and custom Arduino/IDF code used in Home Assistant automation.
Can you safely design high-voltage (110V/220V AC) relay boards?
Absolutely. I follow strict safety standards for mains AC PCB layout, including proper clearance, creepage gaps, optocoupler isolation, and trace slots to prevent short circuits.
Can you optimize the ESP32 board for battery operation and deep sleep?
Yes! I integrate low-quiescent voltage regulators, battery protection ICs, and power-gating FETs so your ESP32 sensor node runs efficiently on LiPo or solar power.
Will I receive production-ready files for PCB fabrication?
Yes! You will get complete Gerber, Pick & Place (CPL), and BOM files configured specifically for automated assembly at JLCPCB, PCBWay, or Seeed Studio.
Which design software do you use?
I design primarily in KiCad and Altium Designer. Native project source files are included in every package, so you retain 100% ownership.
