Description
The Arduino Uno is a microcontroller board based on the ATmega328 chip. The Uno has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connector, a power jack, an ICSP header, and a reset button.
The Arduino Uno differs from all previous boards in that it does not use an FTDI USB to serial chip but an Atmega16U2 programmed as a USB to serial converter.
Arduino Uno Overview:
– Microcontroller: ATmega328
– Operating voltage: 5V
– Input voltage (recommended): 7-12V
– Input voltage (limits): 6-20V
– Digital I/O Pins: 14 (of which 6 provide PWM outputs pin:3, 5, 6, 9, 10, and 11)
– Analog Input Pins: 6
– DC current per I/O pin: 40 mA
– DC current for the 3,3V Pin: 50 mA
– Flash memory: 32 KB (ATmega328) of which 0,5 KB used by bootloader
– SRAM: 2 KB (ATmega328)
– EEPROM: 1 KB (ATmega328)
– Clock speed: 16 MHz

Works as it should!

Nice sign.
Chip can easily be used standalone if needed.
You don't need to buy a new UNO, just a new chip.
