Design circuit Jobs

Circuit Design is the process of designing electrical circuits to create a complete electronic system. A Circuit Designer is responsible for designing circuits, testing the board and components through simulations, troubleshooting any errors, and even prototyping the board by manufacturing a few before completing the entire circuit accurately. Through this intricate process, a Circuit Designer will be able to optimize the design with their expertise and creative talent to push out an efficient product.

Circuit Designers are knowledgeable engineers with a high level understanding of electronics engineering and components that can be used in a circuit. They also possess analytical skills as they must be able to calculate loads, power consumption and sophisticated circuit architecture that involves cause and effects to produce sound results. With extensive knowledge of hardware engineering, Circuit Designers are responsible for hardware selection, board sizing, and routing of signals.

Here's some projects that our expert Circuit Designer made real:

  • Automation systems built through electronic schematics
  • Electrical systems concepted through hand sketches
  • PCB designs implemented through industry standard software
  • High level radio networks designed through detailed concept papers
  • Power efficient circuits delivered with noise reduction features

These projects use both beginner and advanced electrical engineering techniques that our expert Circuit Designers are capable of delivering. With creativity, knowledge in engineering disciplines and product optimization experience, our Circuit Designers create reliable and innovative solutions for our clients’ projects.

We invite you to post your project on Freelancer.com so you can experience what our group of expert Circuit Designers have to offer. With their strong background in electronics engineering and creative problem solving, our freelancers can create dependable and optimized circuits for your project.

    Nucleo eMMC PCB Design 6 zile left
    VERIFICAT

    This project focuses on the design of a PCB replicating the form factor of a Nucleo-F446RE, while retaining all pin headers for Nucleo compatibility. The objective is to seamlessly integrate the THGBMNG5D1LBAIL eMMC storage module into the PCB layout. The design will feature an onboard USB2240 controller with a Micro-B USB interface, facilitating eMMC programming. Specific microcontroller pins, to be provided, will establish connections with the eMMC. All components utilized in the design, including capacitors sourced from Samsung and resistors from Uniroyal, will be procured from JLCPCB to ensure efficient procurement and assembly. For this project, you will need to submit the Altium design files, Bill of Materials (BOM), Gerber files, and pick and place files for manufacturing.
