README
README.mdpi-eliminator
Hardware design for the Pi-Eliminator, a component of the Personal Space Weather Station (PSWS) project. Official documentation for this project can be found at pi-eliminator.
Overview
The Pi-Eliminator is designed to interface with SDR hardware, specifically related to the ClementineSDR and projects involving the LTC2208 ADC. It appears to serve as an interface or replacement for Raspberry Pi-based setups in these systems, featuring standard 2x20 pin headers.

Questions
How big is the Pi eliminator PCB?
It measures 70 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pi eliminator use?
17 parts. 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 Pi eliminator KiCad files?
From the wittend/pi-eliminator repository on GitHub, at the commit this page was made from: the board is pi-eliminator.kicad_pcb and its schematic pi-eliminator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pi eliminator design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
