Overview
Puli's devy is an open-source printed circuit board by tyrobee, from the tyrobee/puli_dev repository on GitHub. It is a 2-layer board of 21 × 51.4 mm with 27 parts on 53 nets, routed with 671 tracks and 53 vias.
It is built around the SK6812MINI-E. Its parts include 14 capacitors, 5 resistors, 4 connectors, 1 IC and 1 diode. It belongs with the microcontroller boards boards of this library.
Main components

README.mdpuli_dev
s a simple dev board based of rp2040. It has everything that I would want on a dev board lots of GPIOs, plenty of grounds, and some other useful features (listed below). This was a fun and pretty easy project to make once I started to understand what I needed to do. It ended up being foundational to my ability to design PCBs, and it showed me how much I enjoy this kind of work. I hope I’ll be able to make even more dev boards later in life
Features
- The RP2040 is the brain of this project handling all of the processing
- this uses the W25Q16JVZPIQ with a whopping 16-Megabit flash menmory
- Usbc this is just a normal USB-C Receptical to send data and also power
- one pin for 5v power and another pin for 3v power
- 9 pins for ground to make it easy to ground everything you need to
- this board comes wih 29 gpio pins 4 of which are dual use for analog inputs (ADC pins)
- also on this board is an led to make it easy to check if the board is powered on od if there any any problems also to help debug or even program
- and finaly a button to enter into BOOTSEL mode so you can program you board.

Questions
How big is the Puli's devy PCB?
It measures 21 × 51.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Puli's devy use?
27 parts, built around the SK6812MINI-E. 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 Puli's devy KiCad files?
From the tyrobee/puli_dev repository on GitHub, at the commit this page was made from: the board is kiCad files/puli's devy.kicad_pcb and its schematic kiCad files/puli's devy.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Puli's devy design in my own project?
Its repository states no licence, so its author keeps all rights: ask tyrobee before reusing the design.
