Waveshare Industrial USB to TTL (D) Serial Cable with FT232RNL Chip Ideal for Raspberry Pi 5 Serial Port Debugging & Development - RS9613

Description:

The USB TO TTL (D) is a high-performance USB to TTL serial converter featuring the original FT232RNL chip. It allows seamless communication between a computer’s USB port and devices operating at TTL logic levels—such as microcontrollers, sensors, and embedded systems. Ideal for serial debugging, firmware uploading, or data exchange with Raspberry Pi 5 and other platforms. Built-in multi-protection circuits ensure stable, reliable operation across multiple systems and environments.
