UNO R3 Development Board MEGA328P ATMEGA16U2 A000066

UNO R3, 2012 new type with an easy to use open source controller, the hardware and the Arduino UNO and no big change, compared the biggest difference is that the USB to serial interface circuit, a switch is a ATMega16U2 of single-chip computer, the cost is increased, the software part as before, no big change.


UNO R3 Development Board MEGA328P ATMEGA16U2 A000066




Stitching changes: beside the AREF sutural added two I2C pins (SDA and SCL, only Analog copy of 4 and 5, are not additional I2C interface), in addition, besides the RESET also added are the two pins, one is IOREF, and can let the extensions board to board, load voltage, the stitching is tell extension board currently on-board voltage is how many (such as UNO is 5 v, and is regarded as a copy of the power pins, it does not provide a level), the other one is after treated with placeholder pins.

  • The RESET circuit is more stable.
  • RESET button position has changed, and moved near the USB interface, it is more convenient.
  • ATmega16U2 instead of 8 u2, this does not mean that there are 16 k flash the R3 can make your code run faster, the update service for the USB interface chip, it means UNO can simulate USB HID in theory, such as the MIDI/Joystick/the rid_device_info_keyboard.
  • The Arduino is a Simple I/o platform based on open source code, and use Java, such as Processing/Wiring of C language development environment, the characteristics of easy to understand. Allows you to quickly use the Arduino do interesting things.
  • The Arduino can be used with some electronic components such as: LED lights, buzzer, buttons, photo resistance, etc.
  • The Arduino development environment based on the principle of open source interface, allows you to free download to use developed more amazing interactive work.

Characteristics of description

  • Open circuit diagram of the original design, the development of software interface for free download, can also be in accordance with the requirements and their modified, download the program is simple and convenient.
  • Can simply use sensors, all kinds of electronic components connection (such as: LED lights, buzzer, buttons, photo resistance, etc.), make all sorts of interesting work.
  • Microprocessor controller (ATMEGA328), using high-speed development interface and the environment are very simple and easy to understand, very suitable for beginners to learn.

Performance description
