README
README.mdrp2040_tft_controller_pcb
RP2040-based controller board for the MI0284QT-11 TFT LCD (ILI9341 controller chip) designed in KiCad.
Future plans are to modify this board to have an FPGA controlling the actual LCD, acting as a GPU, allowing the RP2040 (or another microcontroller) to run more complex programs, see my ili9341_controller repository.

Questions
How big is the Tft controller new PCB?
It measures 87.6 × 35 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Tft controller new use?
44 parts, built around the RP2040, W25Q128JVSIQ and LP2985-28DBV. 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 Tft controller new KiCad files?
From the ryanhaus/rp2040_tft_controller_pcb repository on GitHub, at the commit this page was made from: the board is tft controller new.kicad_pcb and its schematic rp2040.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tft controller new design in my own project?
Its repository states no licence, so its author keeps all rights: ask ryanhaus before reusing the design.
