Adafruit ESP32-S3 TFT Feather - 4MB Flash, 2MB PSRAM, STEMMA QT

The Adafruit ESP32-S3 TFT Feather features a built-in 1.14" IPS colour TFT display (240×135 pixels, ST7789) on the front of the board. Combined with the dual-core ESP32-S3's native USB, Wi-Fi, Bluetooth LE, 4 MB flash, and 2 MB PSRAM, it provides a complete visual IoT platform in the Feather form factor.

The colour TFT connects via SPI using dedicated pins not exposed on the breakout pads, keeping all standard Feather pins available. A secondary low-dropout regulator with GPIO control can independently power down the TFT, STEMMA QT port, and NeoPixel — approximately 80–100 µA in deep sleep with everything off. The backlight has a separate PWM pin for brightness control.
