I am currently developing a battery powered DC variable power supply and I need a PCB created to control it. I would need it to have a buck boost circuit that could do 0vdc-60vdc @5amps as well have a current limiting feature for testing equipment, etc. & perhaps digipots to control the output voltage and current limiting digitally through the menu. I also will be using a TFT LCD to display a menu & to show voltages & current draw, so using an STM32 to drive & control all the logic would be preferable. Im not sure which batteries would be best to use in this so achieve the desired power outputs that I want so perhaps you may have some suggestions for batteries but for whichever batteries it would need a BMS and all protections as well with a USB C recharging circuit for recharging it & finally a power switch to disconnect the battery to the input to turn the device on & off. I attached the case I developed for it to give you a visual of the prototype.

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

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

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.
