Brand N/A Model Funduino uno R3 Quantity 1 Color Blue + white + black Material FR4 Features Atmega16U2 instead 8U2. This update services for USB interface chip Specification Microcontroller: ATmega328 Operating Voltage: 5V Input Voltage (recommended); 7-12V Input Voltage (limits): 6-20V Digital I/O Pins: 14 (of which 6 provide PWM output) Analog Input Pins: 6 DC Current per I/O Pin: 40 mA DC Current for 3.3V Pin: 50mA Flash Memory: 32 KB (ATmega328) of which 0.5 KB used by bootloader SRAM: 2 KB (ATmega328) EEPROM: 1 KB (ATmega328) Clock Speed: 16MHz Application Learning board development board English Manual/Spec http://arduino.cc/en/Main/Software Other Atmega16U2 instead 8U2. This update services for USB interface chip. Theoretically UNO can simulate USB HID such as MIDI / Joystick / Keyboard; 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; More stable RESET circuit. The RESET key position has changed has been moved to the corner near the USB interface board more convenient and press. Packing List 1 x Development board 1 x USB cable (52cm)
