SKU: VE-129 Category: Converters

The PL2303 USB to TTL Serial Converter Module (featuring chipsets like the PL2303HX or PL2303TA) is an ultra-low-cost hardware bridge designed to establish asynchronous serial communication between a computer and a microcontroller. Developed by Prolific Technology, it acts as a virtual COM port on your computer, translating USB standard signals into low-voltage serial data streams. It is one of the most widely produced budget tools for flashing firmware on routers, updating hard drive software, configuring Bluetooth modules, and debugging entry-level electronics.

✨ Key Features

High Economic Value: Offers an exceptionally low-cost entry point for basic serial communications compared to premium alternatives.
Built-in Power Distribution: Outfitted with independent pins to output both 3.3V and 5V power simultaneously to run small external loads.
Short-Circuit Overload Guard: Populated with an onboard 500mA self-recovery polyfuse that instantly cuts current during short circuits to protect the host PC.
Encapsulated Protective Shield: The module version usually comes pre-installed inside a transparent heat-shrink sleeve to insulate the naked circuit board from loose workbench wires. [
