   "description": "Uno R3 Board Compatible with Arduino Uno R3 ATMEGA328P U & ATMEGA16U2 Chip on Board Easy to use with Arduino IDE, just set your board as Arduino Uno and you should be able to flash sketches immediately. Sold with a USB Cable. This is the latest revision of the hugely popular Arduino Uno. It includes the SDA and SCL pins next to the AREF as well as the IOREF pin to make sure that your IO pins are referencing the proper ground. Use the Arduino Uno R3 to learn to code. Learning how to use micro controllers or better understand the world around us. There are a million examples of how to use an Arduino for the first time. This includes an LED connected to Pin 13 already on the board, get up and running immediately working on this board. Technical Specifications: Microcontroller: ATmega328P Operating Voltage: 5V Input Voltage (recommended): 7-12V Maximum Input Voltage: 20V Digital I/O Pins: 14 (of which 6 provide PWM output) PWM Digital I/O Pins: 6 Analog Input Pins: 6 DC Current per I/O Pin: 20 mA DC Current for 3.3V Pin: 50 mA Flash Memory: 32 KB of which 0.5 KB used by bootloader SRAM: 2 KB EEPROM: 1 KB Clock Speed: 16 MHz Downloads Arduino IDE Getting Started with Arduino This product was updated on 15-06-2022 Chip from ATMEGA328P-PU to ATMEGA328P U More Information Same Spec Items - SKU A-2854 Manufacturer CHINA MPN UNO R3 Can be used with -",
