Good value for money
Works well for flashing custom firmware on old devices. The build quality feels sturdy. Would give 5 stars if it came with a protective case.

Perfect for ESP32 Programming
This module works flawlessly with my ESP32 projects. The drivers installed easily on Windows 11, and the connection is stable even during long firmware uploads.

Reliable but small pins
Great performance and consistent data transfer speeds. My only minor complaint is that the pin headers are a bit tight for some jumper wires, but once connected, it's solid.

Compact and efficient
The form factor is perfect for portable projects. I appreciate the clear LED indicators which make debugging communication issues much easier.
Q: Is a driver required for macOS Catalina or newer?
A: Generally, macOS includes native drivers for the CP210x family. However, if not recognized, you can download the latest VCP driver from the Silicon Labs website.
Q: Are the TX and RX pins labeled clearly on the board?
A: Yes, the PCB has silk-screen labels for TXD, RXD, GND, VCC, RTS, and CTS to ensure correct wiring.
Q: What is the maximum baud rate supported?
A: The CP2102-GM chip supports baud rates from 300bps up to 921600bps reliably.
Q: Can I use this to power my Arduino Nano?
A: While the module provides 3.3V or 5V output, it is recommended primarily for data communication. For powering boards, ensure the current draw does not exceed the USB port's limit (typically 500mA).
Q: Does this module support 3.3V logic levels directly?
A: Yes, the board features a voltage selector jumper that allows you to switch between 3.3V and 5V output to match your target device.
