PCB Design Walkthrough Sumo Robot | Embedded System Project Series #3

In the last video, I started going over the hardware of the sumobot by talking about its parts. In this video, I continue by explaining the printed circuit board (PCB) I made to connect them. It's a 2-layer PCB with a microcontroller (MSP430G2553IPW28), two regulators (AMS1117-3.3 and MP2359-5V), two motor drivers (TB6612FNG), and an IR receiver (TSOP382). I designed it in KiCad, an open-source software suite for designing PCBs. 0:00 Intro 0:53 Why PCBs? 1:50 My design 3:13 Schematic 3:48 Power input 4:30 Regulators 6:45 Microcontroller 8:24 Range sensors 9:02 Line sensors 9:45 IR receiver 10:10 Unused pins 10:35 How I program it 11:08 Motor drivers 11:57 Outro 🖥️ Hardware and Software https://github.com/artfulbytes/nsumo_... https://github.com/artfulbytes/nsumo_... Note, going over the project a second time, the code might end up slightly different (better). 🌍 Links GitHub - https://github.com/artfulbytes Website - https://www.artfulbytes.com 👨‍💻About me Hi and welcome. I'm Niklas, an embedded systems engineer from Sweden. On this channel, I make practical videos about embedded systems or, in general terms, about building and programming hardware.
