USB TO UART/I2C/SPI/JTAG

Supports multiple interfaces | Compatible with 3.3V and 5V

 

 

Features

  • Supports USB to 2-ch UART, or USB to 1-ch UART + 1-ch I2C + 1-ch SPI, or USB to 1-ch UART + 1-ch JTAG
  • Supports 2-ch high-speed UART interfaces, up to 9Mbps baud rate, with CTS and RTS hardware automatic flow control
  • Supports 1-ch I2C interface, for easy operating EEPROM through the host computer or programming I2C devices such as OLED and sensor
  • Supports 1-ch SPI interface, with 2x chip select signal pins, capable of controlling 2-ch SPI slave devices at different times
  • Supports 1-ch JTAG interface, can be used with OpenOCD for debugging and testing (Due to the limited testing of chips and software functions, users need to evaluate and test this function on their own)
  • Onboard 3.3V and 5V level conversion circuit for switching the operating level of the communication interface, better compatibility
  • Onboard resettable fuse and ESD protection circuit, provides over-current/over-voltage proof, safe and stable communication
  • Aluminium alloy case with oxidation dull-polish surface, CNC process opening, solid and durable, well-crafted
  • High-quality USB-B and DC connectors, smooth plug & pull, durable and reliable, with anti-reverse protection
