Buzzers and speakers

A 5 V active buzzer and a 4 Ω speaker both make sound, but they need completely different drive circuits.

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.

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.

Level shifters

Pick level shifters by bus behavior: I2C/open-drain, auto-direction push-pull, direction-controlled buffers, or 3 V to 5 V logic. They are not universal adapters.
