README
README.mdKnightly
This repository contains the asset files and non-application source code for Knightly, an automatic chessboard product by Chessington. The board is able to detect its own state, move pieces, and detect moves by human players.
This repository contains SOLIDWORKS CAD files for the board, pieces, clock, and other components, STEP files created in KiCAD for the design of the printed circuit boards, Arduino microcontroller code for the detection of chess pieces, and our final project poster.
Folder Structure
CAD files related to the board are available under Solidworks CAD. CAD files related to the detection PCBs are available under PCB CAD. Microcontroller code for the detection system is available under STMDetection. Application code is available under knightly-app (separate repository).
License
With the exception of our poster and our application code, all asset and code files in this repository are available under CC BY-SA 4.0. See LICENSE.txt for more information.

Questions
How big is the Sensorboard PCB?
It measures 220 × 20 mm and has 2 copper layers, 0.8 mm thick.
What parts does the Sensorboard use?
32 parts, built around the DRV5053VAQDBZRQ1 and CD74HC4067SM96E4. 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 Sensorboard KiCad files?
From the penton1753/knightly repository on GitHub, at the commit this page was made from: the board is PCB CAD/sensorboard/sensorboard.kicad_pcb and its schematic PCB CAD/sensorboard/sensorboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sensorboard design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
