Description
The Arduino Uno R3 development board is a microcontroller board based on the ATmega328P chip mainly used for development and prototyping. It has 14 digital input/output pins (6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. You can tinker with your Arduino UNO without worrying too much about doing something wrong. In the worst-case scenario, you can replace the chip and start over again.
This board is a 100% identical clone, not the original Arduino Uno. We sold many of them and had no problems with these boards. They are high quality 100% similar, but at a much better price. You can be confident that these boards work just as well as the original.
