Overview
Pcb module s8 is an open-source printed circuit board by Open-Air-Foundation, from the Open-Air-Foundation/pcb-module-s8 repository on GitHub, published under the CC-BY-SA-4.0 licence. It is a 2-layer board of 54 × 32 mm with 6 parts on 13 nets, routed with 31 tracks and 0 vias.
README
README.mdAirGradient S8 CO₂ Sensor Module — Hardware
KiCad hardware design files for the AirGradient S8 CO₂ sensor module — a plug-in adapter board that carries a SenseAir S8 NDIR CO₂ sensor in AirGradient air quality monitors.
Overview
A passive 2-layer adapter for the SenseAir S8: two sockets matching the S8's 4-pin and 5-pin headers, with power (5 V) and UART passed straight through to an 8-pin host connector. No regulator or active parts — the S8 runs directly from the host's 5 V rail.
This is the S8-only variant of AirGradient's CO₂ sensor adapter family; the SUNX-only board (SenseAir Sunrise/Sunlight) and the combined S8 + SUNX board live in their own repositories.
Design structure
A single KiCad project in s8/: one schematic sheet and a 2-layer board.

Toolchain
- KiCad 7 (file format 2023-01). All symbols, footprints, and 3D models come from the KiCad standard libraries — the project opens without any extra library setup.
Fabrication
s8/production/ holds the released Gerber set (s8-v1.0.zip; the Gerber filenames inside keep the design's original CO2-sensor-pcb naming).
Versioning & releases
Hardware revisions are tagged on this repository. Per-version release notes and the matching production file set are published on the GitHub Releases page.

Questions
How big is the Pcb module s8 PCB?
It measures 54 × 32 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pcb module s8 use?
6 parts. 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 Pcb module s8 KiCad files?
From the Open-Air-Foundation/pcb-module-s8 repository on GitHub, at the commit this page was made from: the board is s8/s8.kicad_pcb and its schematic s8/s8.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcb module s8 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).
