USB to Serial – PL2303HX Chipset, 5-Pin

The USB to Serial (TTL) Converter Module with PL2303HX chipset provides a reliable and cost-effective solution for connecting UART-based devices to a PC via USB. Designed for development, debugging, and firmware flashing, this compact module converts USB signals to 3.3V/5V TTL serial levels, making it ideal for microcontrollers and embedded systems. The onboard PL2303HX controller ensures stable, high-speed data communication while emulating a traditional COM port for seamless compatibility with existing serial applications.

Featuring a standard USB Type-A interface and a 5-pin TTL output (VCC, TX, RX, GND), this module supports both 3.3V and 5V logic systems. It includes data transmission indicator LEDs for real-time monitoring and a 500mA self-recovery fuse for added protection. The PCB is insulated with a transparent heat-shrink sleeve to prevent short circuits and improve durability. Compatible with Windows, macOS, Linux, and select Android systems (driver support required), this converter is widely used for Arduino, ESP8266, STM32, router firmware upgrades, and general UART communication.
