Key Features
- Genuine CH340G Chip: Built around the authentic WCH CH340G IC for stable, error-free USB-to-serial conversion.
- Wide Baud Rate Range: Supports baud rates from 50 bps up to 2 Mbps, covering virtually all serial communication needs.
- 3.3V / 5V Compatible: Onboard voltage selection or dual-voltage output lets you interface with both 3.3V and 5V logic devices safely.
- Full UART Signal Support: Provides TXD, RXD, RTS, CTS, and DTR lines for complete handshaking and auto-reset functionality on Arduino boards.
- Plug-and-Play Operation: Recognized instantly on most Linux distributions; simple one-time driver install on Windows and macOS.
- Compact Breakout Design: Small form factor with clearly labeled pins for easy breadboard and project integration.
- USB Bus Powered: No external power supply needed - draws power directly from the USB port.
- LED Indicators: Onboard TX/RX LEDs provide real-time visual feedback of data transmission activity.
- Cost-Effective Alternative: Delivers performance comparable to FTDI FT232RL and CP2102 converters at a fraction of the price.
