Product Description
1.Introduction
The keyestudio Leonardo R3 development board is our newest easy-to-use open-source controller. It has twenty-three digital I/O ports, seven PWM ports and twelve analog input ports. Compared with other versions of Arduino using separate USB - Serial conversion chips, it only uses a single Atmega32u4 to achieve USB communication and control. The Atmega32u4's native support USB feature also enables Leonardo to simulate a mouse and keyboard.
2.Specifications

3.Other Related Introduction
Digital IO port: 23 (D0 - D13, D14-MISO, D15-SCK, D16-MOSI, d18-23 [A0-A5])
Analog input: 12 (A0 - A5, D4 - A6, D6 - A7, D8 - A8, D9 - A9, D10 - A10, d12-a11)
Serial communication: D0 (RX) and D1 (TX)
IIC communication: D2 (SDA) and D3 (SCL)
External interrupt: D3 (interrupt 0), D2 (interrupt 1), D0 (interrupt 2), D1 (interrupt 3) and D7 (interrupt 4)
PWM port: D3, D5, D6, D9, D10, D11 and D13
SPI: ICSP pins.Support SPI communication by using the SPI library. It is important to note that SPI pins do not connect to any number I/O pins like UNO, they can only work on the ICSP port.This means that if your expansion board has no ICSP pin connected to the 6 feet, it will not work.
LED: 13. There is a built-in LED on the digital pin 13. When the pins are high level, LED is bright;when the pins are low level,the LED is not bright.
