I will design arduino pcb with uart, spi, i2c, usb, bluetooth and wifi interfaces

Hi, I'm a professional Arduino PCB & embedded hardware designer with 7 years of experience designing factory-ready, communication-enabled PCBs for startups, IoT products, automation systems, and smart devices.

If you need a custom Arduino PCB that supports UART, SPI, I2C, USB, Bluetooth, or WiFi, I will design a reliable, manufacturable, and fully documented board tailored to your project requirements.

I don't just design PCBs I design working products.

What I Will Design

• Custom Arduino-based PCB (ATmega328P, ATmega2560, ATmega32U4, ESP-Arduino, etc.)
• Communication interfaces:
• UART / Serial
• SPI
• I2C
• USB
• Bluetooth
• WiFi (ESP8266 / ESP32 integration)
• Clean, optimized schematic & PCB layout
• Proper grounding, decoupling & EMI-safe routing
• Production-ready design

Components Included on Arduino PCB

• Microcontroller (DIP or SMD)
• USB-to-Serial (CH340 / FT232 / ATmega16U2)
• Voltage regulators (5V / 3.3V)
• Crystal oscillator & timing circuit
• Reset circuit (auto-reset supported)
• Protection components (ESD, reverse polarity)
• Headers, connectors, LEDs, resistors & capacitors
