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

Hello

I help turn your idea into a fully functional, production-ready prototype. I design complete custom PCBs with microcontrollers such as ESP32, ESP8266, STM32, and ATmega, including power supply circuits, battery management and charging systems, sensors, actuators, RF components, antennas, and connectors. I optimize PCB stack-up for signal integrity and EMI control, select cost-effective and available components, and develop basic firmware for testing. You will receive all manufacturing files, including schematics, Gerbers, BOM, and production documents.

• PCB Design by using KiCAD, EasyEDA
• ESP32, ESP8266, STM32, ATmega microcontrollers
• SPI, I2C, UART, RS232, USB protocols
• RF design for 2.4GHz, Wi-Fi, Bluetooth, LoRa, NFC, RFID UHF
• Low power / battery powered boards
• Signal Integrity and EMI
• Stack-up building
• Controlled impedance calculation
• Differential pairs and transmission line routing
• Matching network design
• Arduino and STM32CubeIDE
• Embedded C
• Antenna Design and Tuning with HFSS
• Microstrip Antenna / SMT Antenna solutions
