Comprehensive Review of the SparkFun FT231X Breakout Kit

Introduction

As an avid Arduino enthusiast, I’m always on the lookout for tools that enhance my projects, and the SparkFun FT231X Breakout Kit has been an absolute game changer for me. This versatile kit stands out due to its full UART hardware handshake capability, perfect for anyone looking to work with serial applications. It’s ideal for tinkerers, students, and professionals who need reliable communication between devices.

Key Features

• Full UART Handshake: This feature allows for reliable serial communication, which is crucial when downloading sketches to Arduino, ensuring smooth execution without glitches.

• MicroUSB Compatibility: The common microUSB jack enables easy connectivity with modern devices and power supplies, making setups clean and hassle-free.

• Configurable Voltage Outputs: With the jumper on the back, you can choose between 3.3V or 5V output, giving flexibility depending on your project's requirements.

• DTR Pin Functionality: The DTR pin instead of the RTS pin allows for auto-reset on compatible devices, which simplifies programming and uploading.

• All Pins Broken Out: Having all pins accessible makes the board exceptionally hackable and expandability for custom projects.

Benefits

• Simplifies the programming of Arduino boards with auto-reset functionality.

• Offers flexibility in voltage output, accommodating a range of projects.

• Enhances serial communication reliability with full UART hardware support.

• Reduces cable clutter by utilizing common microUSB connections.

• Boosts your ability to customize projects with all pins available for use.

Real-World Use Cases

• Arduino Projects: Using the FT231X Breakout Kit, I successfully programmed an Arduino Uno, benefiting from the auto-reset feature that saved time during uploads.

• Connecting Sensors: I connected several sensors to an ARM microcontroller using this breakout, enjoying stable and reliable serial communication.

• Learning Serial Communication: As a beginner, I used the kit in a workshop to understand UART communication better and worked smoothly with various devices.

Pros and Cons

Comparison

• FTDI FT232RL: While both provide UART communication, the FT231X offers more flexibility with its DTR feature, making it better for Arduino applications.

• Adafruit USB to TTL Serial Cable: Unlike Adafruit’s model, the FT231X has all pins exposed, increasing its hackability and customization for advanced users.

Conclusion

After extensive use, I highly recommend the SparkFun FT231X Breakout Kit for anyone involved in Arduino or serial projects. It combines reliability, flexibility, and ease of use, making it an invaluable tool in any maker's toolbox.
