11.14 digital input and output port: the working voltage of 5V, each way to the maximum output current and access to 40mA.
(1) serial port signal RX (0), TX (1): connected with the internal ATmega8U2 USB-to-TTL chip, providing TTL level of the serial port to receive the signal.
(2) External interrupt (2 and 3): Trigger interrupt pin, can be set to rising edge, falling edge or trigger at the same time.
(3) Pulse width modulation PWM (3,5,6,9,10,11): Provides 6 8-bit PWM outputs.
(4) SPI (10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK)): SPI communication interface.
(5) LED (13): Arduino dedicated to test the retention of LED interface, the output is high when the LED light, then the output is low when the LED goes out.

12.6 analog inputs A0 to A5: each with 10-bit resolution (ie, 1024 different values), the default input signal range is 0 to 5V

13.AREF: Reference voltage for analog input signal.

14.Reset: When the signal is low, reset the microcontroller chip.

15.DC current: 40mA (I / O port)

16.DC current: 50mA (3.3V port)

17.Flash memory: 32 KB (ATmega328 where 0.5 KB for boot program)

18.Size: 75x55x15mm
