Displays

Character LCDs, SPI TFTs, e-paper modules and larger capacitive-touch TFT panels solve different display jobs. Treat display class, interface, controller, resolution, touch, refresh behaviour, storage, voltage and mounting as separate swap checks.

Displays · TFT & LCD displays · 35 parts

Connectors

Sort passive connector adapters from Qwiic boards, LCD modules and microSD card adapters before assuming anything with the right plug will substitute safely.

Air quality

Choose between MQ gas sensors, VOC/eCO2 indoor-air sensors, true CO2 modules and particulate sensors without treating every air-quality breakout as the same detector.
