Atmega328P-PU Arduino bootloader installed DIP-28

ATmega328P-PU microcontroller preloaded with the Arduino UNO R3 bootloader. This is the standard 8-bit AVR microcontroller used in most Arduino UNO boards and fully compatible with the Arduino IDE.

• Genuine Microchip ATmega328P-PU in DIP-28 package
• Preprogrammed with Arduino UNO R3 bootloader for direct use
• Clock speed: 16 MHz
• Flash memory: 32 KB (0.5 KB used by bootloader)
• SRAM: 2 KB
• EEPROM: 1 KB
• Operating voltage: 1.8 V to 5.5 V
• I/O pins: 23 digital I/O, of which 6 can be used as PWM outputs and 6 as analog inputs

Each microcontroller is programmed and tested individually to ensure reliable operation without errors.
