Product information

Description

The InLine 33307F Serial Converter Repeater Isolator USB 2.0 to TTL 5V Black is a reliable and efficient device designed to bridge the gap between modern computers and TTL/UART serial interfaces. Utilizing the advanced FTDI FT232RNL chipset, this adapter ensures stable communication via a virtual COM port. It features a compact black housing with dimensions of 22 mm width, 75 mm depth, and 11 mm height. Built-in protective mechanisms such as PTC fuses, ESD protection, and protective diodes safeguard connected hardware during data transfer, making it a dependable choice for technical tasks.

Advantages

This serial converter offers stable and continuous data transmission across a wide range of baud rates from 300 b/s up to 3 Mbit/s. The inclusion of a 4-pin screw terminal block for GND, TXD, RXD, and +5 V enables secure and straightforward wiring without requiring soldering or complex connectors. Integrated status indicators for power, transmission, and reception allow for easy monitoring of operational status. Furthermore, the USB-powered +5 V output can directly supply low-current peripheral devices or microcontrollers, reducing the need for separate external power sources.

Suitable for

  • Connecting computers to microcontrollers and development boards
  • Serial communication and hardware diagnostics
  • Device configuration and firmware updates
  • Service and maintenance tasks on TTL/UART equipment
  • Testing and prototyping in electronics development environments

When it may not be suitable

This adapter is not designed for interfacing with devices that require logic levels other than 5V, such as 3.3V systems, unless appropriate level shifting is used. It is also unsuitable for high-power applications that exceed the current supply limits of the USB port and its internal PTC fuses.

Key specifications

  • Host interface: USB 2.0
  • Output interface: TTL / UART
  • Host connector: USB Type-A
  • Device connector: 4-pin screw terminal
  • Chipset: FTDI FT232RNL
  • Logic level: Fixed 5V
  • Supported baud rates: 300 b/s to 3 Mbit/s
  • Dimensions: 22 mm x 75 mm x 11 mm
  • Color: Black
  • Supported operating systems: Windows XP, Windows 7, Windows 8, Windows 8.1, Windows 10, Windows 11, macOS, Linux, Android

How to use

To use the InLine 33307F adapter, first connect the USB Type-A connector to an available USB port on your computer. Install the appropriate virtual COM port drivers if necessary. Connect the target device wires to the 4-pin screw terminal block, ensuring proper alignment of GND, TXD, RXD, and +5 V lines. Once wired securely, you can begin data transmission, configuration, or debugging through your preferred terminal software on your operating system.

What to consider before purchase

  • Verify that your target hardware operates on a fixed 5V TTL logic level
  • Check that your operating system is compatible with the adapter
  • Assess the power requirements of your peripheral devices to ensure they do not exceed the USB supply limits
  • Determine if your application requires screw terminal connections or a different interface type
Usage recommendations: Always double-check your wiring connections against the pin assignment before powering on the system to prevent hardware damage. Keep operating temperatures within the specified range of -40 °C to +85 °C and avoid humid, non-condensing environments beyond recommended limits for optimal longevity.
