ARDUINO UNO IS A MICROCONTROLLER BOARD BASED ON THE ATMEGA328

Arduino UNO R3 Microcontroller Board

Getting Started with 3A Motor Driver Shield and Arduino Uno

Based on the ATmega328. Open-source physical computing platform. RoHS Compliant. The DFRduino Uno USB Microcontroller V2.0board is based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller.

Enhanced and improved, the Arduino UNO R4 Minima is armed with a powerful 32-bit microcontroller courtesy of Renesas. Brace yourself for increased processing power, expanded memory, and a whole new level of on-board peripherals. The best part? Compatibility with existing shields and accessories remains intact, and there's no need to make any changes to the standard form factor or 5 V operating voltage.
