Product Name: Arduino Uno R3 Development Board Model NO.: ATmega328P ATmega16U2 Condition: New Customized: Non-Customized Certification: RoHS, CCC base Material: FR-4 Layers: Single-Layer Mode of Production: SMT metal Coating: Tin Product Name: Arduino Uno R3 Used for: Arduino Uno R3 Type: Atmega328p Atmega16u2 Trademark: Arduino Uno R3 Transport Package: PP Packing Specification: 70g Origin: China HS Code: 8544601300 Product Description ATmega328P ATmega16U2 Kit Microcontroller Card & USB Cable for Electronics Robotics for Arduino Uno Rev3 DIY ProjectsProduct DiscreptionThe Mega is 100% compatible with Arduino IDE and most shields designed for the Arduino mega2560 r3,RoHS CompliantThe chip is Atmega2560-16au and Atmega16u2, same with the official version.Improved and expert version: 1. 0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Due that operate with 3. 3V. The second one is a not connected pin, that is reserved for future purposes.Stronger RESET circuit. Use 5. 5 * 2. 1mm DC barrel jack (compatible with 5. 5 * 2. 5mm DC barrel jack)It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.
