Safe Isolated Design

With onboard unibody power supply and digital isolation, this interface converter offers strong anti-interference, low power consumption, and stable isolated voltage, eliminating the need for extra power supplies.


The onboard TVS provides surge and transient spike voltage suppression, lightning-proof and ESD protection, while the self-recovery fuse and protection diodes ensure current and voltage stability, providing over-current and over-voltage protection, and improved shock resistance.


The FT232RL USB to RS232, RS485, and TTL Interface Converter also features a fully automatic transceiver circuit with no delay, allowing for fast and stable communication between USB and different interfaces without interference.

The onboard TTL serial 3.3V/5V voltage translator can be configured via switch, and the high-quality USB-B and RS232 connectors allow for smooth plug and pull.

Multiple Operating System Support

This interface converter also offers multi-system support for Mac, Linux, Android, and Windows 11 / 10 / 8.1 / 8 / 7.

Durable Aluminium Enclosure

Comes in a solid and durable aluminum alloy enclosure with sandblasting and anodic oxidation, offering both fashion and a good hand feeling.
