Overview
Schems is an open-source printed circuit board by ErickCampos, from the ErickCampos/At-Switch repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 230.6 × 112 mm with 96 parts on 10 nets, routed with 1,016 tracks and 0 vias.
It is built around the LM358 and HT12E. Its parts include 32 resistors, 24 diodes and 8 ICs.
Main components

README.mdAT Switch
This repo describes the construction of non-conventional AT switches:
- Proximity-based, through IR LEDs and IR Sensors
- Puff-based, through piezoelectric disc sensors
The devices can act as independent triggers, and a minimal desktop driver, called JATSD (Jack AT Switch Driver) allow them to be used as a 'mouse click' interface, which communicates with the computer directly via audio P2 3.5mm jack input.

Questions
How big is the Schems PCB?
It measures 230.6 × 112 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Schems use?
96 parts, built around the LM358 and HT12E. 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 Schems KiCad files?
From the ErickCampos/At-Switch repository on GitHub, at the commit this page was made from: the board is at-prox/schems/tx/Tx.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Schems design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
