DEV-09716

Overview

The SparkFun DEV-09716 is a USB to serial bridge module based on the FTDI FT232RL IC. It provides a USB 2.0 interface for UART communication, operating at a default supply voltage of 5V with an optional 3.3V configuration via a solder jumper. The module features a compact SMD 6-pin header footprint designed to match official Arduino pinouts. Key electrical characteristics include TX and RX status LEDs for traffic verification and a DTR pin output that enables auto-reset functionality for connected microcontrollers.

Feature Summary

• FTDI FT232RL USB to serial bridge integration
• DTR pin support for target device auto-reset
• Configurable 3.3V or 5V power and I/O levels
• TX and RX activity indicator LEDs

Applications

• Programming and debugging 5V Arduino boards
• General serial communication interfacing
• Development with SparkFun LilyPad modules

Procurement Notes

Verify the specific hardware revision when sourcing this component, as the current version utilizes a smaller SMD 6-pin header compared to earlier designs. Confirm the required logic voltage level (3.3V vs 5V) before deployment, noting that the board ships configured for 5V operation by default. Ensure compatibility with the target system's connector pitch and pinout requirements.

Selection Notes

Select this module when a reliable USB-to-UART bridge is required for 5V logic systems. It is specifically suited for projects involving Arduino platforms that benefit from the auto-reset feature provided by the DTR line. Consider the 3.3V configuration option if the target application requires lower voltage signaling instead of the standard 5V setup.

Part Context

This breakout board serves as a simplified alternative to the full-size FTDI cable, offering a more permanent and cost-effective solution for serial development. It is frequently paired with SparkFun's Arduino Pro series and LilyPad products, providing a standardized interface for firmware uploads and serial data monitoring in embedded electronics projects.

Replacement Considerations

The SparkFun DEV-09873 offers identical functionality but operates natively at 3.3V logic levels. For applications requiring Micro-USB connectivity, the FT231X Breakout serves as a functional substitute with different physical interface requirements.
