Onboard CP2102 USB Type-C Serial Converter Module

Description

Product Overview

The Onboard CP2102 USB Type-C Serial Converter Module is a high-performance, single-chip USB-to-UART bridge solution designed to provide seamless serial communication between your computer’s modern USB Type-C port and microcontroller-based embedded systems. Based on the industry-standard Silicon Labs CP2102 controller , this module creates a virtual COM port on your computer, allowing you to program, debug, and communicate with a wide range of devices including Arduino, ESP8266, ESP32, STM32, and STC microcontrollers.

The module features the modern USB Type-C connector, offering reversible plug orientation and compatibility with the latest laptops, tablets, and smartphones. Unlike older USB-A adapters, the Type-C interface is future-proof and eliminates the frustration of plugging in the cable the wrong way.

At the heart of this module is the CP2102 chip, which integrates a USB 2.0 full-speed function controller, USB transceiver, oscillator, and EEPROM—all in a compact package, requiring no external resistors or crystal . The module provides both 3.3V and 5V logic level support, selectable via onboard jumper, making it compatible with virtually any target device voltage requirement . Whether you’re flashing firmware onto a router, accessing a Raspberry Pi console, or debugging sensor data, this adapter delivers reliable, high-speed communication with baud rates up to 1 Mbps.
