AVR ATmega328P Project Board
Project and accompanying videos to create a PCB board in Eagle from scratch for hosting an AVR ATmega328P micro controller.
Okay, quick followup post looking at the fine tuning the placement of parts on the 50x50mm PCB board. We continue where we left off last, in part 2. Time Table of Contents 00:00 – Intro 00:09 – Start adjusting placement of ICSP, Reset Switch, and LED 00:58 – Adjust ADC/I2C Header Placement 02:48 – Adjust GPIO Header Placement 03:29 – Adjust XTAL and capacitors 03:55 – Adjust decoupling capacitors 04:57 – Tweaking and adjusting of ICSP, Reset Button, and LED 05:45 – Fine tune placement of headers with Information tool 06:11 – Move ICSP and reset button away from edge of the board 06:55 – Adding copyright marking on the board 07:53 – More fine tuning placements with Information tool. 08:35 – Credits Roll
Welcome to part 2 of the series. In this video, we actually reference the building out of a blank 50x50mm rounded corner board with M3 hole mounts. Since I already had a video like that posted up, I didn’t want to use up too much time to duplicate content. Folks who want to check it out can do so. Rough Placement So the TLDR; of this video segment is that we place parts on the board roughly where we want them to be. Ie, We might want the MCU in the middle of the board so it’s easy to route to it from anywhere? We want the headers for Serial, I2C, GPIO, and ADC to be on the outer edge, where it will be easier to access. We…
So this video runs a bit long, over 40 minutes. I would have broken it up or montaged it, but I wanted to be able to provide information with the option of skipping ahead. This is a beginning to end video of the schematic for the ATmega328P board being created in Autodesk Eagle PCB Design software. All of the parts used in the design are through hole parts and the resources used are listed below. Information From Video Posting So this video runs a bit long, over 40 minutes.
