�� Key Features Compatible with Arduino Nano: Plugs directly into the Nano, breaking out all I/O pins to headers. Breadboard-style layout: Pin labels and layout match the Arduino UNO for easy project adaptation. Onboard power management: Voltage regulator (5V and 3.3V outputs) DC barrel jack or screw terminal for external power Multiple I/O ports: Digital and analog pins broken out to 3-pin headers (Signal, VCC, GND) for easy sensor and module connections I2C and SPI headers: For quick connection to I2C and SPI modules UART (TX/RX) headers Servo motor headers: Pre-wired with power and ground Built-in power and status LEDs Reset button Optional onboard modules (depends on variant): OLED header NRF24L01 socket Bluetooth interface SD card socket RTC socket (DS1307 or DS3231) �� Use Cases Rapid prototyping with sensors, motors, and displays Robotics and automation projects IoT systems with wireless modules Educational electronics learning kits
