Design Philosophy
The OpenFlap system is designed to be modular and expandable, using common components and manufacturing techniques such as 3D printing and printed circuit boards.
The OpenFlap system uses DC geared motors instead of traditional stepper motors. This simplifies the mechanical design and reduces the cost of the system. Additionally this reduces the power consumption of the system and allows the split-flap display to rotate faster than the traditionally used stepper motors.
The OpenFlap system is designed to be as plug and play as possible. The system is able to determine it's own display size, and should only require calibration once.
The OpenFlap system has a web interface that allows local control of the display. The web interface uses a HTTP API to communicate with the display, this API also allows external services to communicate with the display. No authentication or security measures are implemented at the moment.
The OpenFlap system can connect to your local WiFi network or host it's own network.

Questions
How big is the Controller PCB?
It measures 57.9 × 30.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Controller use?
49 parts, built around the ESP32-S3-WROOM-1-N8, XL1509-5.0, AP2112K-3.3 and K24. 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 Controller KiCad files?
From the ToonVanEyck/OpenFlap repository on GitHub, at the commit this page was made from: the board is hardware/controller/src/controller.kicad_pcb and its schematic hardware/controller/src/controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask ToonVanEyck before reusing the design.
