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

Do you need a professional PCB design, schematic, and hardware prototype for your next electronics project? 

I will help you bring your idea to life, I can design a complete board with a microcontroller (ESP32, ESP8266, STM32, ATmega), power supply circuit, battery management and charging circuit, sensors, actuators, connectors, antenna, and other RF components.

What I Offer:

• Complete PCB Design using KiCAD or EasyEDA
• Microcontroller Integration: ESP32, ESP8266, STM32, ATmega
• Power Supply & Battery Management: Charging circuits, low-power designs
• Sensor & Actuator Interfaces: Analog/Digital, SPI, I2C, UART, RS232, USB
• RF Design & Antennas: 2.4GHz, Wi-Fi, Bluetooth, LoRa, NFC, RFID (UHF)
• Stack-Up & Signal Integrity: EMI control, controlled impedance, differential pairs
• High-Speed Routing: Transmission line techniques, matching networks
• Firmware Development: Arduino, STM32CubeIDE (basic board bring-up/testing)
• Manufacturing-Ready Files: Schematics, BOM, Gerber, Pick-and-Place, 3D models

Advanced Capabilities:

• Microstrip & SMT Antenna Design
• Antenna Tuning using HFSS / EM Simulation
• Matching Network Design & Layout
• Expertise in RF layout & shielding techniques
