Questions
How big is the ECS sense PCB?
It measures 155 × 182 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ECS sense use?
176 parts, built around the LMP91000SD, ADS1115IDGS and REF3025AIDBZR. 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 ECS sense KiCad files?
From the mi3nts/PCBMints2026 repository on GitHub, at the commit this page was made from: the board is kiCad/gasSensorV2/ECS_sense.kicad_pcb and its schematic kiCad/EC_Sense_KiCad_10/hardware/EC_Sense_UART_USB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ECS sense design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
