Description
CH341T USB to I2C / UART Adapter is a compact USB 2.0 module built on the WCH CH341T chip that bridges USB to I2C (IIC) and to UART/TTL serial, letting a PC talk to I2C EEPROMs and sensors or act as a USB-to-serial adapter for microcontrollers.
- Two interfaces: USB to I2C (IIC) and USB to UART (TTL serial)
- Onboard 3.3V and 5V rails with selectable logic level
- USB 2.0 full-speed; UART baud rates up to ~2 Mbps
- Common uses: reading/writing I2C EEPROMs and sensors, USB-TTL serial console
- Drivers: WCH CH341 VCP driver on Windows; in-kernel ch341 support on Linux
