Frequently Asked Questions - VMA102 VELLEMAN

How do I power the VMA102?

The VMA102 can be powered via the mini-USB port (5V from computer) or by connecting an external 7-12 VDC supply to the VIN pin. It does not have a DC power jack.

What is the difference between VMA102 and Arduino Nano?

The VMA102 is a compatible clone of the Arduino Nano 3.0. It uses the same ATmega328P microcontroller and pinout, so it works seamlessly with the Arduino IDE and most Nano shields.

How do I program the VMA102?

Connect the board to your computer via a mini-USB cable. Open the Arduino IDE, select the correct board (Arduino Nano w/ ATmega328) and port, then upload your sketch.

What is the pinout of the VMA102?

The board has 14 digital I/O pins (D2-D13), 8 analog inputs (A0-A7), power pins (5V, 3.3V, GND, VIN), and ICSP header. Refer to the manual's diagram for exact layout.

Can I use Arduino shields with VMA102?

Most shields designed for Arduino Nano will fit, but note the VMA102 has a different form factor (45x18mm) and uses mini-USB. Always check pin compatibility before use.

What is the maximum current per I/O pin?

Each I/O pin can source or sink a maximum of 40 mA. The total current from all pins should not exceed 200 mA.

Does the VMA102 have a built-in LED?

Yes, pin D13 has a built-in LED that can be used for testing (similar to the 'L' LED on Arduino Uno).

What precautions should I take when using the VMA102?

Keep the board away from moisture or liquids, use indoors only, and avoid short circuits. Do not expose to extreme temperatures or physical shock.

Can I use the VMA102 with a breadboard?

Yes, the VMA102 is breadboard-friendly with its pin headers on 2.54mm pitch. It's designed to fit directly into a breadboard.

How do I reset the VMA102?

Press the reset button on the board. You can also reset it via software using the DTR signal from the USB connection.

4. What is Arduino ®

Arduino ^ is an open-source prototyping platform based in easy-to-use hardware and software. Arduino ^ boards are able to read inputs – light-on sensor, a finger on a button or a Twitter message – and turn it into an output – activating of a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so, you use the Arduino programming language (based on Wiring) and the Arduino ^ software IDE (based on Processing).
