Lilygo T Dongle S3 Esp32S3 Development Board Wifi Bluetooth

You power rapid IoT prototyping with a compact ESP32‑S3 development board engineered directly into a USB‑A dongle that provides native Wi‑Fi and Bluetooth Low Energy.

• The optional 0.96‑inch ST7735 display renders serial logs and system status directly on the board, eliminating the need for an external HDMI adapter.
• A concealed microSD socket stores project files and SDIO cards safely inside the clear shell, though you must slide a standard card into the housing before unplugging to shield the metal contacts.
• You flash firmware instantly via the USB bridge using Arduino, PlatformIO, or MicroPython environments, making it ideal for wireless gateway devices, RFID readers, and BLE trackers.
• Choose the K193 model for the integrated screen or the K194 model for a bare‑bones layout tailored to your current design phase.
