The WCH CH341T is a USB-to-serial converter chip from Nanjing Qinheng Microelectronics (WCH), designed for reliable USB-to-UART communication in embedded and industrial applications. It supports standard asynchronous serial interfaces and is commonly used in microcontroller development boards, USB-to-TTL adapters, and communication modules. The CH341T requires an external crystal oscillator and is supported on Windows, Linux, and macOS through official WCH drivers. With stable data transfer, low power consumption, and a proven design, the CH341T is a cost-effective solution for serial communication, debugging, and device configuration in both hobbyist and professional environments.
