Solid build quality
Bought this for my son's science fair project. The PCB feels sturdy, and the pin headers are well-soldered. We got the Bluetooth module working within an hour using standard libraries.

Reliable for classroom use
We purchased ten of these for our high school robotics club. They have held up well under frequent plugging and unplugging by students. Highly recommended for educational settings.

Perfect for my robot car project
This expansion board made assembling my Bluetooth-controlled robot car incredibly easy. The servo ports are clearly labeled and the L293D driver handles the motors without overheating during short test runs.

Great value for learning
As a beginner, I found this board very helpful for understanding motor control. The only reason for 4 stars is that the silkscreen printing is a bit faint, but functionally it works perfectly with my UNO.

Good integration, minor heat issue
The board integrates seamlessly with the Arduino IDE. Just be aware that if you run both motors at full speed for extended periods, the driver chip gets warm. A small heatsink might help for long missions.

Exactly what I needed
I was struggling to wire up servos and motors separately. This shield cleaned up my wiring instantly. The Bluetooth slot is a nice bonus feature that I plan to use next.
Q: Does this board come with the Bluetooth module included?
A: No, the expansion board includes the socket for the Bluetooth module (HC-05 or HC-06), but the module itself must be purchased separately.
Q: Can I power the motors directly from the USB port?
A: No, USB power is insufficient for motors. Please use an external 7V-12V DC power source connected to the barrel jack or VIN pin to drive the motors effectively.
Q: Do you provide sample code for the motor driver?
A: Yes, this board uses the standard L293D chip. You can use any existing Arduino library for L293D motor drivers, and we have example sketches available in our documentation repository.
Q: Is this compatible with the Arduino Mega 2560?
A: While the pin spacing matches, some pins used for specific functions on the UNO shield may map differently on the Mega. It is primarily designed and tested for the Arduino UNO R3.
Q: What is the maximum voltage the servo ports can handle?
A: The servo ports share the input voltage supplied to the board. Ensure your external power supply does not exceed the voltage rating of your specific servos, typically 5V or 6V.
