LILYGO T-Dongle-S3 ESP32-S3 Development Board With Built In LCD Screen

You can prototype compact wireless sensor nodes directly on a USB-A styled ESP32-S3 module that delivers instant system diagnostics via a built-in screen.

• Debug your application logic using the embedded 0.96‑inch ST7735 display instead of relying solely on serial output.
• Mount your mainboard securely within the clear protective housing, which reveals active IO pins while preventing accidental electrical shorts during bench testing.
• Store custom configuration files in the recessed memory compartment, remembering to leave a physical microSD card installed when detaching the device.
• You quickly download verified source repositories and community scripts for complex Bluetooth mesh networking, long-range LoRa telemetry, and basic home automation tasks.
