Ideal for programmers, hardware engineers and DIY enthusiasts.Compared to other USB to TTL UART adapters, this adapter not only supports 3.3V and 5V logic levels, but also adds support for 1.8V and 2.5V logic levels.At the same time it is equipped with a protective plastic case, this protective plastic case can effectively prevent static interference and various short circuits.

Compatible with 1.8V, 2.5V, 3.3V, and 5V TTL levels, ideal for diverse electronics projects requiring flexible voltage communication.

In addition to the basic pins (UART TX/RX/RTS/CTS/VCC/GND), DSR/RI/DCD/DTR/RESET pins are individually accessible. Supports a variety of control needs.

Includes a transparent case to prevent static interference and accidental short circuits, enhancing durability during use.
