- Uses the original FT232RL for USB communication, delivering fast, stable, and reliable data transfer with broad compatibility across major operating systems. Built-in protection circuits include over-voltage and over-current protection. Important note: there is no protection between the two power supplies of the host terminal. - Onboard unibody power supply isolation provides a stable isolated voltage with no extra power supply required for the isolated terminal. Onboard unibody digital isolation isolates the signal, delivering reliable, jam-proof operation with low power consumption. - Onboard TVS (Transient Voltage Suppressor) effectively clamps surge voltages and transient spikes in the circuit, enhancing protection against lightning and electrostatic discharge. - Onboard resettable fuse and protection diodes ensure stable current and voltage outputs, provide over-current and over-voltage protection, and improve shock resistance. Practical applications - USB to serial communication for microcontroller and embedded development: compatible with development boards and peripherals that rely on FT232RL, enabling fast, stable data transfer with robust protection in place. - Isolated data transmission in bench and industrial environments: the unibody power and digital isolation help protect sensitive equipment and maintain signal integrity when interfacing with sensors, measurement devices, or control systems. - Prototyping, testing, and educational labs: reliable protection from surges and ESD, plus stable outputs and broad OS compatibility, support safe experimentation and learning with various USB-serial projects.
