What's this?
Node Zero is an rp2040 based micro-controller unit that consist of the rp2040 micro processor, the 16Mbit SPI NOR Flash, a crystal oscillator that synchronizes communication in the board between the USB abd rp2040, a voltage regulator, reset and boot switch.
Why I built it ?
This is the starter project of stasis and I have not make any dev board ever before, so this is my the first time I am making an dev board so I am very excited to build this. That's why I am making the PCB whole custom thing. I have also get help from the detailed guide that is provided on the stasis website.

Questions
How big is the Node Zero PCB?
It measures 21 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Node Zero use?
47 parts, built around the RP2040, W25Q128JVSIQ and ICM-20602. 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 Node Zero KiCad files?
From the Sadrita404/Node-Zero repository on GitHub, at the commit this page was made from: the board is PCB/Node Zero.kicad_pcb and its schematic PCB/Node Zero.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Node Zero 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).
