README
README.mdThis project is an open source project to build TFT board using RA8875 IC from RAiO (http://www.raio.com.tw/index.htm). The goal of this board initially is for 5inch screen but for next versions will support all the way to 7inch.

Questions
How big is the RA8875 PCB?
It measures 39.9 × 43.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RA8875 use?
22 parts, built around the TPS61040DBV and MIC5225YM5. 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 RA8875 KiCad files?
From the nanikjava/RA8875 repository on GitHub, at the commit this page was made from: the board is ra8875.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the RA8875 design in my own project?
Its repository states no licence, so its author keeps all rights: ask nanikjava before reusing the design.
