FeatherS3 ESP32-S3 with u.FL by Unexpected Maker

Introducing the FeatherS3 - The pro ESP32-S3 Development Board in the Feather Format now with a u.FL connector instead of an onboard antenna, for the times when you want to connect an external antenna for longer radio range, or for putting your S3 boards inside a case/enclosure.

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.
