Arduino Uno R3 Development Board (ATmega328P)
Microcontroller: ATmega328P-based development board.
Naming: "Uno" means "one" in Italian, marking the release of Arduino 1.0.
Input/Output:
14 digital I/O pins (6 capable of PWM output).
6 analog input pins.
Clock & Memory:
16 MHz ceramic resonator.
32 KB Flash memory (0.5 KB used by bootloader).
2 KB SRAM, 1 KB EEPROM.
Power Options:
Can be powered via USB or external supply (6-20V).
Recommended supply voltage: 7-12V.
Power source selection is automatic.
Unique Feature: Unlike previous boards, the Uno R3 uses the Atmega16U2 (Atmega8U2 in earlier versions) as a USB-to-serial converter, instead of the FTDI chip.
External Power Details:
AC-to-DC adapter (2.1mm center-positive plug) or battery.
Gnd and Vin pin headers for battery connection.
Voltage regulator considerations: less than 7V may cause instability; more than 12V may overheat and damage the board.
Electrical Specifications:
Operating Voltage: 5V.
Maximum Supply Voltage: 20V (not recommended).
DC Current per I/O Pin: 40 mA.
DC Current for 3.3V Pin: 50 mA.
Clock Speed: 16 MHz.
