Specifications

Key Features

• Genuine CP2102 Chip: Silicon Labs CP2102 ensures stable, error-free serial communication with wide OS driver support.
• Dual Voltage Output: Provides both 3.3V and 5V on breakout pins, compatible with ESP8266, ESP32, Arduino Pro Mini, STM32, and other 3.3V/5V logic boards.
• Full UART Signal Breakout: Exposes TXD, RXD, DTR, RTS, CTS, and GND pins for complete handshake and auto-reset functionality.
• DTR Pin for Auto-Programming: DTR output enables one-click firmware upload to Arduino Pro Mini, ESP8266, and similar boards without manual reset.
• Plug-and-Play USB: Recognized instantly on most operating systems - install the CP210x driver once and you're ready to go.
• High Baud Rate Support: Supports baud rates up to 1 Mbps for high-speed serial data transfer and debugging.
• TX/RX LEDs: Onboard activity LEDs give instant visual feedback during data transmission and reception.
• Compact & Breadboard-Friendly: Small form factor with standard 2.54mm pitch header pins fits directly into breadboards and prototyping setups.
• USB Bus Powered: No external power supply needed - draws power directly from the USB port.
• ESD Protection: Built-in electrostatic discharge protection on the USB interface for safer operation.

Why Choose This CP2102 Module?

• 100% authentic Silicon Labs CP2102 IC - no counterfeit clones that cause driver headaches
• Tested and verified before dispatch for reliable out-of-the-box operation
• 1-5 day shipping, 7-8 day delivery from our Bengaluru warehouse across India
• Expert technical support to help with driver installation, wiring, and troubleshooting
• Trusted by thousands of makers, students, and engineers nationwide

Common Applications & Project Ideas

• Arduino Pro Mini Programming: Connect TXD, RXD, DTR, VCC, and GND to upload sketches directly from the Arduino IDE - the DTR pin handles auto-reset.
• ESP8266/ESP32 Firmware Flashing: Use with NodeMCU flasher or Arduino IDE to program ESP modules that lack onboard USB - wire DTR to GPIO0 for auto-flash mode entry.
• Serial Debugging & Monitoring: Open a serial monitor (PuTTY, Arduino Serial Monitor, CoolTerm) to read sensor data, debug code, and monitor real-time output from any UART device.
• Raspberry Pi Serial Console: Access the Pi's UART console for headless setup, boot debugging, and kernel log monitoring without a monitor.
• GPS Module Interface: Read NMEA data from GPS modules (NEO-6M, NEO-7M) directly on your PC for testing and data logging.
• GSM/SIM Module Communication: Send AT commands to SIM800L, SIM900A, and similar GSM modules for SMS, call, and GPRS testing.
• Bluetooth Module Configuration: Enter AT command mode on HC-05/HC-06 Bluetooth modules to change name, baud rate, PIN, and master/slave roles.
• STM32 & Bare
