A look at the Band Surfer VFO ESP32-S3

In this video, I delve into the ESP32-S3 based Band Surfer VFO, demonstrating its functionality by connecting it to an old 11-meter transceiver. I also guide you through the process of compiling the C++ code, along with the necessary libraries, using the Arduino IDE.

If you encounter any challenges, don't hesitate to reach out to me at [email protected]. I'm considering creating a FAQ video to address common questions about this project.

Join me as we explore the capabilities of this innovative VFO and learn how to implement it in your own projects!

SPI TFT LCD Screen RGB Touch Display Module ILI9341
NOTE: The LCD driver IC used in this video is the ILI9341 320x240 pixel.
The code will only support this IC at this time.
2.2", 2.4", 2.8" or 3.2" sizes will work fine.
Also we are using a no touch display but a touch will work fine but
the VFO has no touch control functionality.
