Learn how to start a new PCB project, place components, and improve your schematic in this comprehensive tutorial video. Begin by setting up units and grid, defining the board shape, and strategically placing power components. Progress to positioning the microcontroller, accelerometer, and RGB LED, followed by the remaining components. Explore the process of selecting an appropriate LDO regulator, including checking maximum current and power dissipation considerations. Enhance your design by replacing components, adding series resistors, and fine-tuning the layout. Gain valuable insights into PCB design best practices and component selection criteria throughout this step-by-step guide, which is part of a larger series on designing and building a simple microcontroller board.
