Specifications
Microcontroller: ATmega328P, an 8-bit AVR processor from Atmel.
Operating Voltage: 5V (regulated), with a 3.3V output available for
certain low-power components.
Input Voltage: Can be powered by a USB cable (5V) or an external
power supply (7-12V).
Digital I/O Pins: 14 pins, 6 of which provide PWM (Pulse Width
Modulation) output, useful for controlling servos, LEDs, and
motors.
Analog Input Pins: 6 pins that read voltage levels, useful for
reading data from analog sensors like temperature, light, and
potentiometers.
Flash Memory: 32 KB for storing programs, with 0.5 KB used by the
bootloader.
SRAM: 2 KB, where the program’s variables are stored during
execution.
EEPROM: 1 KB for permanent data storage, allowing the board to
retain data even when powered off.
Clock Speed: 16 MHz, which determines how quickly the processor
can execute instructions.
Connectivity: USB Type-B connector for programming and
powering, along with a barrel jack for external power.
