DFRobot UNO R3 Board Compatible with Arduino Uno R3 | ATmega328P-PU Microcontroller + ATMega16U2 USB Communication

DFRobot UNO R3 Board Compatible with Arduino Uno R3 | ATmega328P-PU Microcontroller + ATMega16U2 USB Communication

Compatible with Arduino UNO R3 and Arduino IDE: this low-cost DFRobot UNO R3 board is specifically designed for Arduino beginners and enthusiasts with the same pin layout as the official version. 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. Easy to use: This UNO R3 board is equipped with an Atmega16U2 USB-to-serial chip. When it's connected to a computer, the OS automatically detects the USB-to-serial chip and installs the necessary drivers to enable the UNO R3 board to communicate with the computer and transfer data. Color-coded headers for easy identification and connection: the headers use different colors to feature I/O ports of different types: Red for Power Section, Blue for Analog I/O, Green for Digital I/O. This makes the UNO R3 board is easy to figure out where to connect sensors, or to identify which side is Analog (blue) or Digital (green). ATmega328 (DIP Package): the maincontroller chip used is ATmega328 (DIP Package), allowing users to easily swap out different programs or troubleshoot by simply plugging and unplugging the chip. It also enhances prototype design and testing efficiency. Abundant Tutorial Project Eesources and High-Quality Technical Support: You can find a wealth of tutorials, project cases, and more on the DFRobot Community. If you encounter any issues during the product usage, you can access top-notch technical support services. DFRduino UNO R3
