Hello, I fully support your opinion. I also amazed at your deep knowledge of electronics. Your measurement project is a general industrial frequency, and although the principle is simple, relatively high voltage and large current can cause problems. I have a lot of experience with your project and here are my opinions: 1. A buffer circuit that can match the current voltage and current (considering the peak) to the inlet of the ADC element (in the microcontroller) is required. 2. The resolution of ADC is 18bit and the sampling frequency is 6kHz (2*3*18*60Hz) or higher. 3. The cutoff frequency of the low-pass filter for noise suppression is less than 500Hz (9*60Hz). *The low-pass filter can be realized numerically in the microcontroller. 4. You need a mini USB port for programming and a PCB and Gerber file for final production. 5. BOM file is required for element purchase and cost calculation as a closing. Please reply if my opinion is right. Thanks.

Hi, good afternoon, I am an Electronics Engineer specializing in PCB design for Embedded Systems and Power Electronics, I have checked the complete requirement list detailed and I can ensure that I am the right person to develop this project. I detail next my related experience: * Schematic and layout design using KiCAD V6. Symbol and footprint libraries creation and management. * Analog frontend design for high resolution, high precision sigma-delta ADCs. * Protection circuitry for power electronics systems. * MCUs of several manufacturers, including Texas Instruments and ST microelectronics. Experience in the embedded industry. C/C++ programming experience. * CANBUS and other industrial grade protocols I will first design your system at "System level", detailing block diagrams and main components, such as the MCU and ADC. Then will perform all the needed software simulations using LTSpice and create a report. After that, will choose all the commercial components, prepare a BOM and create the schematic. Next comes the firmware development and first stage debugging. Finally, will perform the layout design and create all the corresponding manufacturing files. After the PCB has been built, the final testing and debugging stage will be performed, ensuring that all works as expected. Please contact me so we can discuss this further, PD: Feel free to ask me about previous designs so you can see what quality you can expect from my work. Regards,

Hello! I have experience with hardware development for 3+ years. I've developed a hobby project of board which intended to measure current of load by current transformer and voltage by resistive divider. You can find it in my portfolio. I used Kicad for this.

Hello to the team, I have more than 12 years experience in Electronic hardware development. Most recently I worked for Pepperl+Fuchs company in Mannheim (Germany). In my last two projects I worked on analog-digital measurement for a temperature transmitter (using ADS1248 from Texas Instruments) and universal power supply, which can serve 19..30VDC and 90...230VAC. I would be glad to support you in the project. I live at the Slovenian border in Austria and could even provide on-site support (e.g. qualification measurements, EMC measurements, etc.). It has been a long time since I have done a layout. For this job you could hire an experienced freelancer-layouter. Would be pleased about a feedback. Kind regards. André Erz
