PL2303 USB to TTL Serial Converter Module – 3.3V/5V UART Bridge for Arduino & ESP32 Programming

Overview 

The PL2303 module is a cost-effective USB-to-UART bridge. It allows your PC to communicate with any serial device by creating a “Virtual COM Port.” Whether you are flashing firmware to an ESP32, debugging a Raspberry Pi, or reading data from an industrial sensor, this module provides a stable, low-latency connection.

Key Features 

• Dual Voltage Logic: Built-in jumper allows you to switch between 3.3V and 5V output, ensuring compatibility with different microcontroller logic levels.

• Plug-and-Play (Driver Dependent): Installs as a standard COM port on Windows, Linux, and macOS.

• Diagnostic LEDs: Onboard TX and RX LEDs provide visual confirmation of data flowing in both directions.

• Self-Recovery Fuse: Includes a 500mA resettable fuse to protect your computer’s USB port from accidental shorts.
