SMUGDESK CP2102 USB 2.0 to UART TTL 6PIN Serial Converter Module

SKU CH-4TZD-NZ7NY

USB 2.0 to UART TTL serial converter module with CP2102 chip for MCU debugging and firmware flashing

  • CP2102 chip delivers stable USB 2.0 to TTL UART conversion
  • 6-pin header enables quick wiring without soldering
  • Supports MCU debugging and firmware flashing tasks
  • Compact module fits easily into DIY project enclosures
  • Plug-and-play operation works with mainstream computer systems

USB 2.0 UART adapter for development

The SMUGDESK CP2102 module converts a USB 2.0 port into a 6-pin TTL serial interface using a built-in CP2102 chip. It is intended for engineers, hobbyists and technicians who need reliable serial communication for microcontroller debugging, firmware flashing or sensor data capture.

Check driver and voltage compatibility

Before ordering, confirm that your host computer can install the CP2102 virtual COM port driver for your operating system. Verify that the target device operates at the same logic voltage as the module to avoid signal-level mismatch.

Steady throughput for long debug sessions

The converter maintains consistent baud-rate stability during extended firmware uploads or continuous serial logging without the timing drift sometimes seen in short-burst tests. Its compact board layout also resists heat buildup when left powered for hours in a lab or field setup.

Questions about this item

What comes in the box and what else do I need to connect it?

The package contains one CP2102 USB 2.0 to UART TTL 6PIN serial converter module. You will need a USB cable and jumper wires or a 6‑pin header to wire it to your target device.

Which version or capacity should I choose for my project?

This listing offers a single CP2102 based module with a standard 6‑pin layout; there are no alternative versions or capacity options to select.

What does the CP2102 chip actually do when I plug it into my computer?

The CP2102 chip converts the USB 2.0 signal into TTL‑level UART serial data, letting the host PC communicate with microcontrollers, sensors or other serial devices at standard baud rates.
