I will build esp32 iot controller pcb with nfc authentication

Hello there!

Are you looking to build a custom ESP32 IoT controller PCB with NFC authentication for your smart project? Youre in the right place.

I specialize in designing compact, low-power, battery efficient ESP32 based PCBs tailored for real world IoT applications.

Unlike generic development boards, I design optimized PCB's that reduce power consumption, save space, and improve reliability perfect for battery powered IoT systems.

What I Can Do For You:

• Custom ESP32 PCB design (small, efficient & production-ready)
• NFC authentication integration (secure access systems)
• Battery powered design with charging circuit (Li-ion / LiPo)
• Low-power optimization (deep sleep, efficient regulators)
• Buck/Boost power supply design (stable 3.3V output)
• Sensor & peripheral integration (I2C, SPI, UART, ADC)
• Programming interface (FTDI / external flashing)
• Battery voltage monitoring circuit

Why Choose Me?

Clean, professional PCB layouts (SMD optimized)

Designed for real-world manufacturing

Focus on low power consumption & compact design
