Arduino Nano shield

From the shop's description

Arduino Nano shield An Arduino Nano shield is an expansion board designed to enhance the functionality of the Arduino Nano by providing additional connectivity, easier wiring, and expanded features. These shields typically include breakout headers, power management, and additional I/O interfaces to simplify prototyping and circuit design. Features: Plug-and-Play Compatibility where designed to fit the Arduino Nano directly, eliminating the need for complex wiring. Breakout Pins where provides easy access to GPIO, PWM, I2C, SPI, UART, and analog inputs. Power Options where may include voltage regulators, allowing external power sources (e.g., 7-12V DC input) and providing 3.3V and 5V outputs. Additional Modules where some shields integrate relays, motor drivers, LCD interfaces, or sensor connectors. Screw Terminals & Headers for secure connections with external devices, sensors, or motors. Prototyping Area where many models include a small breadboard-style or PCB prototyping area for custom circuits. Specification: DC power connector: 5 V to 12 V 14 pins of I/O in configuration servo (with power and ground) 8 analog pins with the ground and power 6 pins PWM 1 input of power supply of servo The I2C port The UART port AREF output Output 3.3 V Board sizes: 57 x 53 x 12 mm Applications: IoT projects. Home automation. Robotics. Industrial control. Wearable technology.
