The Athena Board is a 3-D printer control board that interfaces with an Orange Pi Zero

Thermally controlled dynamic pattern textile component.
Thermal AR Tile is an open-source printed circuit board by bkaccelerator, from the bkaccelerator/thermo-variable-pattern-tek-tile repository on GitHub. It is a 2-layer board of 69.2 × 40.6 mm with 15 parts on 11 nets, routed with 55 tracks and 2 vias.
It is built around the PSMN022-30PL. Its parts include 4 resistors, 3 connectors, 2 ICs, 2 diodes and 2 transistors. It belongs with the wearables boards of this library.

A thermochromic dye makes fabric respond to heat by turning white. Digitally-controlled heaters sewn into the material then allow the overall pattern to be controlled by a computer.
One application is in augmented reality. The pattern can be tracked in space by a device's camera to allow digital graphics to be overlaid. By varying the pattern a garment can then communicate with devices using it for augmented reality effects.
TEK-TILES is a project from the Brooklyn Fashion and Design Accelerator to develop examples of new textile technologies.

It measures 69.2 × 40.6 mm and has 2 copper layers, 1.6 mm thick.
15 parts, built around the PSMN022-30PL. 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.
From the bkaccelerator/thermo-variable-pattern-tek-tile repository on GitHub, at the commit this page was made from: the board is hardware/PCBs/Thermal AR Tile/Thermal AR Tile.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask bkaccelerator before reusing the design.
