USB to TTL Converter CP2101 (5 Pin)

Key specifications

  • Chipset: Stable and reliable Silicon Labs CP2102/CP2101 USB to UART bridge chip.
  • USB Compliance: USB 2.0 compliant, supporting full-speed 12 Mbps data transfer.
  • Operating Voltage:
    • Features pin interfaces for both 3.3V and 5V power output to the target device.
    • The logic levels (TX/RX signals) are also adjustable between 3.3V and 5V depending on the module design.
  • Baud Rates: Supports a wide range of baud rates, typically from 300 bps up to 1 Mbps or 1.5 Mbps.
  • Buffers: Includes integrated transmit and receive buffers (e.g., 512-byte transmit buffer and 512 or 640-byte receive buffer).
  • Handshaking: Supports hardware (RTS/CTS) or X-On/X-Off handshaking.
  • Protection: Often includes a 500mA self-recovery fuse to protect the computer’s USB port from accidental short circuits.
  • Operating Systems Support: Compatible with various operating systems, including Windows (98SE, XP, Vista, 7, 8, 10), Mac OS-X/OS-9, and Linux.
  • Interface Pins: Standard pins usually include 3.3V, 5V, TXD (Transmit), RXD (Receive), and GND (Ground). Some versions also expose DTR and RTS signals.
  • Temperature Range: Designed to operate in a wide temperature range, typically from -40°C to +85°C.
