README
README.mdIRIS2 network radio project. This repository will contain all the necessary information required to build the unit.
Project images and video clips: https://drive.google.com/open?id=105BILNTAdYNRVomJvfbO0CPW3QA1uIXu
Currently we have here:
- Code for core Iris application along with all necessary system scripts
- KiCad projects/schematics for all PCB's
- STL's of all parts of the IRIS2 case
- Some initial documentation
What we need to add:
- More documentation
- Detailed assembly instructions for all the PCB's and the unit itself
- Detailed BOM for all of the PCB's, and additional stuff required to assemble the unit itself
- Detailed instructions on how to make your own copy of IRIS2 firmware based on Raspbian (and/or firmware images)

Questions
How big is the RTC Board PCB?
It measures 65 × 56.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RTC Board use?
17 parts, built around the AT24C512N and DS1307Z+. 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 RTC Board KiCad files?
From the woytekm/IRIS2 repository on GitHub, at the commit this page was made from: the board is Hardware/RTC Board/RTC Board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RTC Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask woytekm before reusing the design.
