Type-C Serial Adapter Module with PL2303 Onboard Chip

Description

Product Overview

The Type-C Serial Adapter Module with PL2303 Onboard Chip is a modern, high-performance USB to UART (TTL) converter designed to bridge the gap between your computer’s USB Type-C port and microcontrollers, routers, and embedded systems. This adapter provides a reliable solution for programming, debugging, and serial communication with a wide range of devices.

Featuring the PL2303 series chip from Prolific Technology, this module delivers stable serial communication with support for both 3.3V and 5V logic levels, making it compatible with popular development boards such as Arduino, ESP8266, ESP32, STM32, and Raspberry Pi . The reversible USB Type-C connector ensures easy plug-in orientation and compatibility with the latest laptops, tablets, and smartphones.

The module includes onboard status LEDs (PWR, TXD, RXD) for real-time visual feedback of power and data transmission activity, simplifying troubleshooting and debugging . The VCCIO jumper setting allows flexible power configuration—you can power your target device directly from the adapter (3.3V or 5V) or have the target device supply the logic reference voltage (1.8V/2.5V/3.3V/5V) .

This adapter is an essential tool for electronics hobbyists, embedded systems developers, and network engineers who need to access console ports, flash firmware, or debug serial communication on modern computing devices that lack legacy USB-A ports.

Key Features

• USB Type-C Connector: Modern reversible connector for easy plug-in; compatible with the latest laptops, tablets, and smartphones

• PL2303 Chipset: Based on Prolific PL2303 series (GS/HXD variants) for stable USB-to-UART bridge performance

• Adjustable Logic Level (VCCIO): Supports 1.8V, 2.5V, 3.3V, and 5V via onboard jumper—compatible with a wide range of target devices

• 3-in-1 Power Modes: Three operational modes via jumper setting:

  • 3.3V Output: Short jumper to 3.3V pin

  • 5V Output: Short jumper to 5V pin

  • External Power: Remove jumper, VCCIO powered by target board

• Dual Power Supply Capability: The chip can be powered either by USB bus power (taking about 35mA) or by an external 3.3V supply

• Status Indicator LEDs: Onboard PWR (power), TXD (transmit), and RXD (receive) LEDs for real-time communication monitoring

• Full Duplex Asynchronous Communication: Supports data rates up to 12 Mbps with true full-duplex operation

• Modem Control Signals: Provides full set of modem handshake signals (RTS, CTS, DSR, DTR, DCD, RI) and hardware flow control

• Wide OS Compatibility: Supports Windows XP/7/8/10/11, macOS, and Linux; drivers available for all major platforms

• Plug-and-Play: Hot-pluggable with automatic COM port configuration by the operating system
