Hi, I am an experienced electrical design engineer. I am expert in circuits design in eagle software. I have more than 5 years of experience in curcuits and PCB designs. I will be using two mosfets to switch voltages using a pin of microcontroller. 0V at pin will switch output voltages to 3V and 1 at pin means output voltages will be 5V. P channel mosfets are highly reliable for delivering power. Power capabilities will be max 2.8A per channel. Let me know if you have any questions. Thank you.

Hi, I am a professional electrical engineer I know all about circuit and layout design on cadence mentor and synopsys, etc…. and have all the required cad tools on my laptop I can finish your task quickly and efficiently, you can see my works in circuit design in my portfolio. Thanks

hi sir i can complete this job. i am expert in arduino programming. come to chat to discuss more. waiting for a reply from you. i have work on sucb things before.

I have more than 5 years experience in embedded systems and electronic circuit design . so I can do your job within a time limit with your satisfaction.

Hello, my name is George Bouris. You, actually, have two options for this project: 1. Increase the voltage of the 1st regulator by 1V (if you don't use its output to supply other components) and make the 2nd regulator to switch between 5V and 3.3V. If this is possible, it's the most elegant solution. 2. Use a mechanical relay. If I correctly understand your design, you need good accuracy for the output voltages. For this, you can't use MOSFETs to switch between the two voltages - they will affect the accuracy of the output voltage. Also, if you use MOSFETs, you may still need to increase the output voltage of the 1st regulator.

Dear you, I have 6 year experiences to design circuit using Altium. My project have been manufactured at the factory, so i will give you the best result. Brg!

Hi My name is Vusi and I'm an Electronic Engineer with over 5 years of development experience. You can learn more about me from my Freelancer profile.

i will make this very quickly and provide you with a simulation. .

Hello I can finish your project quick and very price effective. There are few options to design this, together we can pick the best one for you. Please check some of my electronic design references below: ** I have experience for 6 years on over 45 projects that include professional R&D of hardware. They have included general schematics & PCB design in various areas, including, but not limited to: microcontroller design, communication systems such as mobile and GPS, digital communications. I have also worked written code for embedded microcontrollers and Linux systems. ** Best regards, David

Hi, the best way is to use MOS-FET transistors. In your configuration, you can use small and cheap mos-transistors in SOT-23 packages. The uC you use, can control the transistors in a easy way, The overall circuit will be small and reliable. Do you need also the PCB or just the schematic of it? I can help you with both... Cristian

Since the 2000s I have been working on electronic circuit’s projects in the areas of video, audio, microcontrollers and automation. For over 8 years I work with P-CAD projects including the following tasks: Creating a schematic drawing (.shc) from a rough draft or idea. Creating the component library ("Symbol" and "Pattern"), if they are not available in the default library. P-CAD. Creating the layout (.pcb) according to the schematic (.shc) The layout can be single layer, double layer or multilayer. The components to be assembled may be surface, with through hole or a combination of both. It is recommended that the minimum size of SMD components to be used is 1.00 x 0.50 mm (402). According to the project requirements, the designs may include the following layers: top, bottom, internals, silk, top / bottom mask, top / bottom solder; in Gerber files and accompanied by a list of components (.bom)

I've done this before. It is easy. Do you want the circuit diagram, or the program? Please give me more information.

We have a design office, so we are a god team from world , USA,UK,FRANCE. We can do it easy. About the price we have the lower price in the world with a good quality of services and shot timing. So have a nice day and good luck.
