README
README.mdKlink
Klink is a magnetic tile system for building programmable machines. First up: a marble run with sensors, buttons, lights, gates, splitters and an elevator.
V1 requires at least 16 smart tiles and a motorized elevator for continuous circulation. The power budget also targets 24-32 tiles in suitable grids. Each tile is 80 × 80 × 20 mm, with four neighbor connections and two RGB LEDs. A Hub will handle USB, layout discovery and programs that run without a computer.
Rev A uses a 20V bus, with 5V and 3.3V made on each tile. The schematic is in place, but the connectors and protection still need testing. The PCB isn't routed. Disconnect power before moving tiles.
Hardware sources are in hardware/electronics/ and hardware/cad/. Firmware, SDK and Studio are still planned work.

Questions
How big is the Elevator PCB?
It measures 60 × 44 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Elevator use?
51 parts, built around the ATTINY404-SSN, AP2112K-3.3TRG1, RC0805FR-0710KL and RT0805BRD0710KL. 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 Elevator KiCad files?
From the Bruhdows/klink repository on GitHub, at the commit this page was made from: the board is hardware/electronics/elevator/elevator.kicad_pcb and its schematic hardware/electronics/elevator/elevator.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Elevator design in my own project?
Its repository states no licence, so its author keeps all rights: ask Bruhdows before reusing the design.
