- Onboard protection features include self-recovery, diode-stable current and output, plus overcurrent and overvoltage protection to improve reliability in various operating conditions. - Featuring the original FT232RL chipset, it provides stable, high-speed USB-UART communication that is compatible with standard FT232R interfaces. - External three LED indicators clearly display power, transmit, and receive activity for quick, at-a-glance status checks. - USB to R8485 communication bridge enables straightforward data exchange with R8485-based devices and systems. - Practical use scenarios: - Microcontroller development and debugging: connect to common MCUs (for example, AVR, STM32, PIC) to program, monitor, and debug via USB-UART. - Embedded system prototyping and testing: use as a reliable USB-UART interface to log data, send commands, and validate R8485 communication links. - Maintenance and QA in production or labs: quickly verify serial communication and activity with clear LED indicators during testing.
