Versatile USB Conversion: The usb to uart/i2c/spi/jtag converter supports USB to dual UART channels, USB to 1 UART + 1 I2C + 1 SPI, and USB to 1 UART + 1 JTAG. It provides two high-speed UART interfaces with baud rates up to 9Mbps, featuring CTS and RTS hardware flow control. 2. Comprehensive Interface Support: The usb to uart/i2c/spi/jtag interface converter includes one I2C interface, making it easy to operate EEPROMs or program and control I2C devices (such as OLED displays and sensors) from your computer. 3. Enhanced SPI Control: The usb to uart/i2c/spi/jtag adapter converter offers one SPI interface with two chip select pins, allowing time-sharing control of two SPI devices from your computer. 4. Reliable JTAG Debugging: The converter supports one JTAG interface, suitable for debugging and testing with open-source OpenOCD (note that device and software compatibility may vary; users should evaluate specific device and software usage). 5. Robust Design and Compatibility: The interface converter features built-in 3.3V and 5V logic level conversion circuits, enhancing compatibility. It includes onboard resettable fuses and ESD protection circuits to prevent overcurrent, overvoltage, and electrostatic discharge, ensuring stable and secure communication. The aluminum alloy casing, with anodized sandblasting and CNC precision openings, ensures durability and craftsmanship. Equipped with high-quality USB-B and DC power connectors, it provides smooth and reliable plug-and-play functionality, preventing reverse connection. Compatible with Windows 7/8/8.1/10/11, Linux, and other operating systems.
