As an Electrical Engineer with a penchant for circuitry design and development, I possess the proficiency you need for your ESP32 Circuit project. My understanding of safety standards coupled with my extensive experience in voltage measurement, particularly in the range of 440vac, make me the ideal candidate for this job. In line with your project requirements, my Electronics and PCB Design expertise equip me to intricately craft accurate circuits that align with your needs. Additionally, I bring to the table a mastery of MATLAB, which is essential given your output preference in numerical data formats. With this adept knowledge and skillful application, I will ensure not only accurate voltage measurements but also offer comprehensive solutions that optimize performance. Arguably, one of my major differentiators is my dedication to quality and reliability. By choosing me for this project, you can rest assured knowing that rigorous testing and validation will be conducted throughout the process to guarantee an end-product that exceeds your expectations. Together, let us forge ahead in making your voltage measurement needs a reality - backed by precision and proficiency.

PROJECT PHILOSOPHY: A system measuring 400VAC using an MCU is pretty straightforward. A PCB shall be designed to have the required ports data transmission line. Estimated project duration: 2-3 weeks. PROJECT SUBMISSION: The following documents will be provided during the final project submission: 1) PCB Gerber 2) PCB Component Assy file 3) JLC PCB / LionPCB Fabrication Drawing 4) Component BOM 5) Cost Breakdown 6) MCU src code (if required) PROJECT SPECS INFO 1) Using a low-density MCU like an STM32F103 series shall be more cost-efficient and easy to implement. An ESP32 is an overkill for this application. 2) Suggested data (measurement) transmission via CAN line. If wireless capability is required, we shall implement a separate PCB base away from the source line. 3) Adequate safety devices will be provided: Short circuit fuse protection, ESD and EMI protection. ** Required information about current rating, type of source transmission, surrounding environment and dimension constraints. Happy to find this amazing offer. Looking forward to connecting with you and contributing to your business.
