Chipset: FT232RL, not FTDI chip. Working voltage: 3.3V / 5.5V. RXD / TXD transceiver communication indicator with a 500 mA selfrestore fuse for protection and visibility during data transfer. Pin definitions: DTR, RXD, TX, VCC, CTS, GND. Linux compatibility: Compatible with Linux operating systems and widely used by Linux users. Key benefits Reliable USB to serial bridge for Linux development and everyday use. Flexible voltage support (3.3V or 5.5V) to match a variety of devices. Onboard RXD and TXD indicators help monitor activity and troubleshoot connections quickly. Builtin 500 mA selfresetting fuse provides protection against overcurrent and short circuits. Simple sixpin header layout (DTR, RXD, TX, VCC, CTS, GND) enables straightforward wiring to microcontrollers and single board computers. What makes it stand out Uses the FT232RL chipset while identifying as not FTDI, offering a costeffective alternative without compromising core USBUART functionality. Strong Linux compatibility and popularity among Linux users, making setup and support more straightforward for Linuxbased projects. Use scenarios Programming microcontrollers from a Linux PC: Connect TXD and RXD to the target board, use DTR for auto reset, and power via VCC while monitoring activity with RXD/TXD indicators. Serial console and debugging on Raspberry Pi or similar Linux boards: Establish a stable serial link for console access, logs, and troubleshooting with CTS for flow control. Data logging and testing of custom embedded devices: Use the USBUART bridge to collect serial output from embedded hardware under Linux, benefiting from the protected power path and clear activity indicators.
