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

Application Environments: suitable for college students, technical engineers, electronic enthusiasts, or DIY makers for learning and debugging
