Model: X1301 - Quantity: 1 - Material: Immersion alloy plate - Color: Multicolored - Arduino UNO R3 is the new model open-source controller the USB to serial port circuit is a ATMega16U2 single chip - The pin change: 2=I2C pin are added next to the AREF (SDA and SCL it the same as Analog 4 and 5 no need other I2C interface); And 2-pin are added next to the RESET one is IOREF to let the expansion board adapt the on board voltage they just show the on board voltage the other is standby occupied pin - More stable RESET circuit the RESET button is moved to the corner of board next to the USB interface more convenient to press - ATmega16U2 replaces the 8U2 it is serviced for USB interface chip to let the UNO analog USB HID such as MIDI / Joystick / Keyboard - Arduino starter kit singlechip set - Packing List: - 1 x Arduino uno R3 module - 1 x USB cable (62cm) - 2 x Breakboards - 25 x Breakboard connection cables (11cm) - 30 x Carbon film resistors 100R - 30 x Carbon film resistors 1K - 30 x Carbon film resistors 4.7K - 30 x Carbon film resistors 10K - 30 x Carbon film resistors 47K - 30 x Carbon film resistors 100K - 30 x Carbon film resistors 1M - 2 x Single-link potentiometers 10K - 2 x Single-link potentiometers 100K - 3 x F5 LED green - 3 x F5 LED red - 3 x F5 LED yellow - 3 x F5 LED white - 6 x Soft touch switches - 3 x Soft touch switches (white square) - 3 x Soft touch switches (white round) - 3 x Soft touch switches (green square) - 3 x Soft touch switches (blue round) - 3 x Soft touch switches (red round) - 2 x Single row pins
