This shield is specifically built to enhance the capabilities of the Arduino Nano, simplifying the process of connecting external sensors or actuators. It extends the functionality of the Arduino Nano by providing accessible IO (Input-Output) pins organized in a convenient 3-way header pin configuration, reminiscent of RC servo and RC receiver connections, which is a common format for many sensors and actuators. Beyond the SVG (Signal, Voltage, Ground) header pins, this shield also offers dedicated pins for UART and I2C, each represented by a 4-way header pin. With the inclusion of Ground (GND) and 5V (V) pins on every expanded IO header, you'll never have to worry about sourcing power and ground connections for RC servos and sensors. One standout feature of this IO expansion shield is its ability to power the Arduino Nano through an external power adapter. The shield features a DC Barrel jack (2.1mm) for plugging in a standard power adapter. It incorporates a reverse polarity protection diode and a capacitor to smooth out voltage ripples from the adapter. Additionally, an independent 3.3V voltage regulator is included, capable of delivering extra current (up to 500mA), supplementing the 3.3V output from the Arduino Nano (limited to 50mA from the FT232 IC). This shield is designed in the shape of a traditional shield, providing additional side pads for Arduino UNO header pins. A notable advantage is the clear labeling of all header pins, ensuring ease of use.
