Nano Expansion Prototype Shield v3.0

This multi - function expansion board for Arduino Nano is a great addition to your setup. It leads out all digital and analogue IO ports, each equipped with a standard positive and negative power interface. The I2C interface of the mainboard is also led out for easy connection. Moreover, it has an added DC power supply interface. The current supplied by the Nano USB interface is only 50MA, which is not enough for high - current devices like servos. With the DC power connector, it can provide external power to ensure stable operation of your equipment.

Using this expansion board is easy. First, connect it to your Arduino Nano. You can use the led - out digital and analogue IO ports to connect various sensors or other devices. The standard positive and negative power interfaces make it simple to power these connections. To connect devices that need the I2C interface, just use the led - out I2C interface on the board. When using high - current devices, remember to connect the DC power supply through the DC power connector. This will give your equipment the power it needs for stable operation. As for maintenance, keep the board clean and dry. Avoid exposing it to extreme temperatures or humidity. If you notice any loose connections, check and tighten them carefully. That's all you need to know to make the most of this great expansion board.
