Overview
Valentino is an open-source printed circuit board by Sreeram-Ramesh, from the Sreeram-Ramesh/KiCad-Projects repository on GitHub, published under the MIT licence. It is a 2-layer board of 60 × 64.7 mm with 19 parts on 34 nets, routed with 388 tracks and 50 vias.
It is built around the ATMEGA328-AU and MIC5504-3.3YM5. Its parts include 9 capacitors, 2 resistors, 2 ICs, 2 connectors and 1 diode. It belongs with the AVR (ATmega, ATtiny) boards of this library.

README
README.mdKiCad Projects
An archive for all my KiCad project folders for various projects I've been working on. Find more about each of these KiCad projects on their respective repos if they exist wherein I have shared about the project itself, here's a quick overview of my KiCad designs.
Overview
Several attempts were made by me in the past to try out designing and printing PCBs for my personal high school projects. After constant yapping and getting my dad on-board for my PCB fab through JLC PCB, results were pretty bad cuz of my PCB design skills. Some pictures for context. Fast forwarding now, I understood high-school me was pretty dumb, or always that has been the case and I am living in delulu.
With all that being said here are some of my recent projects.
1. 555 ID Badge
This project served as a great introduction for me in KiCad. I am grateful to Digikey and Shawn Hymel for their open-source project (resources below). Through this, I learned to create custom footprints, read datasheets, search for specific IC components for projects, and design according to the capabilities of the service provider.
2. Pravega - The Line Follower
Working on an agile line follower bot utilizing the PID control algorithm. This project is being developed in association with the Build Club SSN college. Looking to quickly realize it and bring it on the competitive stage.
3. Valentino
A development board, similar to the arduino, based on the ATMEGA328 chip, design brought to life on the Valentine's day. Pretty rudimentary design. Looking forward to my microcontrollers course in semester 4. Hoping to develop more on this and have my custom microcontroller board made one day. If you have got any resources you think can help me kindly let me know. Here are some specs:
- Clock Speed: 16 MHz
- Supports SPI and UART
- Can be worn as a locket
- 16 GPIO pins in total
Feedback
If you have any feedback for my work, or maybe would like to thank me for any of my custom footprints that you somehow found useful, or have some useful resources, please mail it to my email.

Questions
How big is the Valentino PCB?
It measures 60 × 64.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Valentino use?
19 parts, built around the ATMEGA328-AU and MIC5504-3.3YM5. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Valentino KiCad files?
From the Sreeram-Ramesh/KiCad-Projects repository on GitHub, at the commit this page was made from: the board is Valentino/Valentino.kicad_pcb and its schematic 555Badge/555Badge.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Valentino design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
