I will make hardware prototyping, schematic, pcb design, esp32, esp8266, stm32, arduino

I develop electronic hardware prototypes from circuit concept through schematic, PCB design and embedded controller integration. I work with ESP32, ESP8266, STM32, Arduino and other MCU platforms for IoT devices, automation, robotics, sensor systems and custom electronics, considering power, interfaces, board dimensions and manufacturing requirements from the design stage.

WHAT I DEVELOP

• Hardware architecture & component selection
• Circuit schematic capture & review
• Single, double & multilayer PCB layouts
• ESP32, ESP8266, STM32 & Arduino hardware
• Sensors, displays, relays, motors & actuators
• Wi-Fi, BLE, CAN, RS485, UART, SPI & I2C
• Regulators, battery charging & protection circuits

PROTOTYPING & ENGINEERING

• Breadboard/module prototype integration
• Grounding, decoupling & power integrity
• EMI/RF-aware placement & routing
• Programming/debug interfaces & test points
• ERC/DRC and DFM/DFA verification
• PCB/enclosure clearance checks

DELIVERABLES

• Editable schematic + PCB source files
• Gerber + NC Drill package
• BOM + Pick-and-Place files
• PDF schematic & fabrication notes
• Optional STEP/3D PCB model
• Prototype assembly/testing guidance

NDA available.
