Using FT232RNL chip solution, high-speed communication is stable, reliable, and offers good compatibility. It adopts half-hole technology and features a compact design, making it convenient for users to weld, integrate, and embed. Supports serial communication rates from 300 bps to 3 Mbps. Onboard self-resetting fuse and ESD protection provide stable current and voltage output, protecting against overcurrent and overvoltage for safe and stable operation. Integrated serial port transceiver indicator light allows real-time signal status monitoring. VCC switching pad is provided; default setting is 3.3V TTL, which can be modified to 5V by cutting and soldering. All functional pins of the chip are brought out to facilitate integration and secondary board use. Features a Type-C interface for smooth, secure connection that prevents reverse insertion. Product type: USB to UART TTL level Supply voltage: 5V Serial port (TTL level): 3.3V/5V Communication rate: 300 bps to 3 Mbps Compatible with: Windows 7/8/8.1/10/11, Linux, Android, WinCE Color: Blue Material: PCB Package Contents: 1 x Serial Communication Module Note: The package includes only the items listed above.
