A Step by Step tutorial to help everyone to learn how to design and build a simple microcontroller board. This Part 3 is about how to start a new PCB, how to place components and what to think about when selecting an LDO regulator. Here is the finished project where you can see how this board is used: - Making a Magic Wand with Light Effects and Spell Recognition | Wizards Wand https://youtu.be/D_asM2Lh_I0 Download the finished Schematic and PCB here: https://oshwlab.com/robertferanec/myboard Download the project source code from here: https://github.com/FEDEVEL/youtube-tiny-simple Watch the full tutorial here: https://youtube.com/playlist?list=PLXvLToQzgzdea0sQXmpY8k4tfiXpkYIwO Individual videos: - Tutorial #1: How to Design and Build Your Own Board - Simply and Easily https://youtu.be/_x2fzKEjUGQ - Tutorial #2: Drawing Schematic and Connecting Microcontroller + Accelerometer ( EasyEDA ) https://youtu.be/m-aDN5mFt7Q - Tutorial #3: Starting a new PCB, Placing Components, Improving Schematic https://youtu.be/OMtdirj2ltE - Tutorial #4: How To Do PCB Layout (Step by Step) https://youtu.be/8TUHE6TFy1A - Tutorial #5: Improving Your PCB Layout and Manufacturing Your Board https://youtu.be/yptbPYe1BL0 - Tutorial #6: Useful Steps To Do After You Receive Your Boards From Production + Some soldering tips https://youtu.be/UTkluwr2KOw - Tutorial #7: How to Write Software And Program Your Board - Step by Step https://youtu.be/e6YTg-UrKes Chapters: 00:00 - Setup Units and Grid 00:58 - Define board shape 01:33 - Placing components (Power) 12:57 - Placing MCU, Accelerometer and RGB LED 21:25 - Placing rest of the components 31:43 - Finding a new LDO 36:47 - Checking Max current for LDO 59:51 - Replacing LDO 1:10:25 - Replacing Debug Header 1:12:14 - Adding series resistors 1:14:06 - Place header and power 1:17:00 - About LDO Power dissipation 1:23:28 - Placing series resistors 1:26:26 - Removing 3D models ------------------------------------------------------ Would you like to support me?
