T-Dongle-C5 get it now

Overview

LILYGO T-Dongle-C5 is a compact ESP32-C5-based USB dongle development board in a standard USB Type-A plug form factor. Powered by the ESP32-C5 single-core RISC-V @ 240 MHz with dual-band Wi-Fi 6 (2.4 GHz + 5 GHz) and Bluetooth 5.0 LE, it integrates a 0.96-inch ST7735 IPS color TFT (80 × 160), a TF card slot, 16 MB Flash, and 8 MB PSRAM — all within a transparent USB-A housing. Thread and Zigbee 3.0 support makes it a versatile platform for next-generation IoT applications, wireless display dongles, and Matter-ready devices.
