LILYGO has released T-Dongle-C5, an ESP32-C5-based small dev board that targets engineers, students, and makers who needed capabilities of a powerful wireless connection in a dongle-sized form factor. This is a high-performance processing with a sleek design, which makes it a perfect gadget for IoT prototyping, network testing, and portable security sites.
Specifications and features
The T-Dongle-C5 core consists of an advanced ESP32-C5 MCU. This chip has the advantage of being dual-band Wi-Fi with support for 2.4 GHz and 5 GHz (Wi-Fi 6) to use along with Bluetooth 5. It has Wi-Fi 6 (802.11ax) to enhance efficiency and stability in dense wireless networks with many devices and the 5 GHz frequency range to enable higher data rates and lower interference than 2.4 GHz-only boards.
ESP32-C5 dev board hardware overview
Large features are implemented in a small dongle. It features an in-built and sensitive ceramic antenna to ensure the presence of a strong signal. In visual feedback, it has a 0.96-inch ST7735 IPS LCD with a resolution of 80×160. It is a full-colour (65k) display with a 4-wire SPI interface, requiring no additional hardware and consuming less power, making it ideal for displaying sensor or system status or custom graphics.
The board has extensive memory capability in terms of complex tasks with 16MB of Flash and 8MB of PSRAM. It also has a slot of TF card (Micro SD), which can be used to increase storage capacity to store data or run small web servers. Measuring just 58 x 18 x 9mm, it consume 5v, 500mA power via USB,
Flexibility and software support.
The T-Dongle-C5 is very easily available to the developer community, featuring the support of both the Arduino IDE and the ESP-IDF (Espressif IoT Development Framework). This makes sure that, no matter whether you are a hobbyist who wants to do a quick setup or you are a professional who is doing a strong industrial application, the software ecosystem available on GitHub is there to help you.
Price and availability
The LILYGO T-Dongle-C5 is being sold at the standard price of already $13.02. On the issue of availability or stock status, the products page presents the product as ” Sold Out”. Additionally, the company has noticed a Spring Festival show between February 10 th and February 25th 2026, which at the same time can affect shipping and restock orders.
