Hello Sir I have an Honors degree in Electronic Engineering and I have over 6 years experience developing embedded applications and PCBs. I also have C and C++ Certifications here on Freelancer and you can learn more about that from my Freelancer Profile. I developed a BMS for a custom Pixhawk design based on STM32 for 48V batteries last year. How about a private message so we can discuss the details of your project. Kind regards V.T

I am a professional PCB design engineer i have expertise in PCB and circuit design for industrial level products. I can help you to reduce the cost of the board, dealing with industrial level-based PCB and circuit to make it cost effective and design improved is my daily routine. I have more than 4 years of experience as hardware design engineer. I am working as hardware design engineer in a reputed firm based in Germany, where my job is to analyze the working of electronic circuit and bring new improved design for our costumer. I understood the project description i can deliver your task as per your requirements at a reasonable budget. Your satisfaction will be my priority, you can trust on me. I am sure you will consider me for this task when you take a look to my portfolio. Looking forward to your earliest response. Best Regards Muhammad Adeel

I can create a PCB for your battery-powered DC variable power supply that includes a buck-boost circuit (0-60VDC @5A), current limiting feature, digital control of output voltage and current through digipots, an STM32 for control and logic, battery management system with protections, and USB-C charging circuit. I can also suggest battery options to achieve desired power output. Let's work together to bring your prototype to life

Good day, I have 30 years of experience in PCB and Power Supply design and I am the best fit for your project requirements. I can design PCB to battery powered DC variable power supply for you in a quality and timely manner. I have seen the attached images you shared and I will do this project quickly. I would like to have a thorough discussion on this project as there are certain suggestions from my side After dedicating more than 30 years to the electronics design and development, I am passionate in designing the best products Technology wise I have worked on all the latest technologies like GSM, 5G, Lora, Battery Powered DC Variable Power Supply etc. And have worked on more than 20 design tools for designing and simulation purpose Some of the generic queries from my side are: 1. What is the application of this product? 2. What will be the ambient temperature of this product? 3. What are the mechanical constraints to be taken care of? If you are someone who wants to benefit from my experience just message me Hi and I shall be there for you Regards Hari Mohan

Greetings This is Umair. I am a practicing Engineer and design various structures. I can do this task and have a great command in the field of Electronics, Microcontroller, PCB Layout, Circuit Design and Electrical Engineering. I can do this task for you on a reasonable price and the quality of work would be up to the mark. However, some questions are still needed to be answered from your side if we interact I will wait for your reply to complete your task within a reasonable time. Thanks & Regards Umair A.

⭐⭐⭐⭐⭐ Power supply PCB design Expert here ⭐⭐⭐⭐⭐ Hi, sir! I can handle your "Portable Power Supply" project as you like. I am an experienced ALTIUM DESIGN, PCB and PCB layout DESIGN developer with the skills necessary to do this. I can start immediately. I will give you good results. I am a perfectionist and I will not be satisfied until you are satisfied. I look forward to hearing from you. Thanks!

Hi, first an explanation about it takes so long: it's because I do actually build and test the prototypes and if I need parts they can take days if not weeks to be delivered, this is of course not under my control. Second: you'll not have to pay me until the project is completed. This said, there are a lot of options about the realization of the circuit, moreover in the box you've sent the picture of I think that the battery will not fit: If you want to provide 5A @ 60V That's 300W plus efficiency and electronics (display etc.) that would need to be feed as well. I don't like to wast your time "boasting" how good I'm: I have a 100% completion ratio and 5 stars, so if in doubt check my references and portfolio. May I ask to chat a little with you to understand exactly your needs before I'm eventually chosen ? One thing: I will just ask you to pay for the plain expenses, perhaps I should buy more than one prototype with more than one integrated circuit and perhaps even more than one PCB. In any case we're talking of few bucks. All the best, Alex.
