Overview This USB to UART/I2C/SPI/JTAG converter is a compact multi-interface tool designed to help you control, program, and debug common serial-bus devices directly from a PC.
It supports flexible working modes: USB to 2-channel UART, USB to 1-channel UART + 1-channel I2C + 1-channel SPI, or USB to 1-channel UART + 1-channel JTAG, making it suitable for lab bring-up, firmware development, and interface testing. For serial communication, it provides 2-CH high-speed UART up to 9Mbps, including CTS/RTS hardware automatic flow control for more stable data transfer. For peripheral access, the device offers USB to I2C for tasks like operating EEPROM and programming I2C devices, and USB to SPI with two chip-select pins, allowing time-sharing control of two different SPI slave devices. The converter also supports USB to JTAG mode for debugging and testing workflows (often used with tools such as OpenOCD). To improve compatibility across target boards, it includes an onboard 3.3V /5V level conversion circuit for switching interface logic levels. Built-in ESD protection and a resettable fuse help improve safety and stability during development and field testing. Housed in a durable CNC aluminum alloy case, it supports Windows (Win7/8/ 8.1 /10/11) and Linux, and offers wall-mount and DIN-rail mount options for tidy bench or cabinet setups. Package include 1.
