Key Features of CP2102 USB to TTL
- 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.
- 100% authentic Silicon Labs CP2102 IC - no counterfeit clones that cause driver headaches
CP2102 USB to TTL Converter Module
Reliable USB-to-UART bridge module powered by the Silicon Labs CP2102 chip, ideal for serial communication between your PC and microcontrollers.
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
