## Description

This compact DFRobot microcontroller bundle is designed for learning, prototyping and physical computing projects. The DFRduino Uno V3.0 is fully compatible with Arduino UNO R3 and the Arduino IDE open-source development environment, which uses the Processing / Wiring language.The board is based on the ATmega328 and includes the essentials for getting started: USB connection, power jack, ICSP header and reset button. It also features an ATmega16U2 programmed as a USB-to-serial converter, plus a DIP package AVR chip that can be removed for firmware updates, reprogramming or use in a finished compact project.Colour-coded headers help make connections clearer: red for power, blue for analogue I/O and green for digital I/O. The kit includes DFRduino Uno V3.0 x1, Gravity: IO Expansion Shield for Arduino V7.1 x1, and USB Cable A-B for Arduino Uno/Mega x1.Features:Arduino compatibility: Fully compatible with Arduino UNO R3.IDE compatibility: Works with the Arduino IDE open-source development environment.Programming language: Implements the Processing / Wiring language.Standalone projects: Can be used to develop stand-alone interactive objects.Computer-connected projects: Can be connected to software on your computer, such as Flash, Processing and MaxMSP.Operating system support: Open-source IDE is available for Mac OS X, Windows and Linux.USB-to-serial: Features the ATmega16U2 programmed as a USB-to-serial converter.DIP AVR chip: Removable DIP package AVR chip for updating or reprogramming firmware, or placing into a finished project.Power header colour: Red for Power Section.Analogue header colour: Blue for Analog I/O.Digital header colour: Green for Digital I/O.Sensor cable matching: Header colours match DFRobot sensor cables.Core hardware: Includes 14 digital input/output pins, 6 analogue inputs, a 16 MHz crystal oscillator, USB connection, power jack, ICSP header and reset button.I2C pins: Added SDA and SCL pins near the AREF pin.Shield support: IOREF pin allows shields to adapt to the voltage provided from the board.Reserved pin: Includes a not connected pin reserved for future purposes.Specifications:Microcontroller: ATmega328 (DIP Package)Operating Voltage: 5VInput Voltage (recommended): 7 ~ 12VInput Voltage (limits): 6 ~ 20VDigital I/O Pins: 14 (of which 6 provide PWM output)Analog Input Pins: 6DC Current per I/O Pin: 40 mADC Current for 3.3V Pin: 50 mAFlash Memory: 32 KB of which 2KB used by bootloaderSRAM: 2 KB (ATmega328)EEPROM: 1 KB (ATmega328)Clock Speed: 16 MHzSize: 75 x54 x15 mm (2.95 x2.13 x0.59")Environment Friendly: Rohs ComplianceA handy starter bundle for Arduino-compatible projects, classroom use, robotics, sensors and general maker development.
