v1.0

Baseline release of the AirGradient S8 CO₂ sensor module — the S8-only adapter in production use.

A passive 2-layer adapter for the SenseAir S8 NDIR CO₂ sensor: two sockets matching the S8's 4-pin and 5-pin headers, with 5 V power and UART passed straight through to an 8-pin host connector. No regulator or active parts.

Attached: s8-v1.0.zip — the released Gerber production set (the Gerber filenames inside keep the design's original CO2-sensor-pcb naming).

Design files are in KiCad 7 format and use only KiCad standard libraries.
