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

I will help you bring a project to life from scratch, all the way to a fully functional prototype ready for production. 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. I can guide you in choosing the stack-up to minimize signal integrity and EMI issues. I can also write the basic firmware for testing the board. Ill help you pick the right electronic components based on your budget and whats available on the market. And Ill provide you with all the necessary files for board production.
