Overview: This is a new SainSmart Leonardo R3 kit, which is easy for Arduino fans and starters to plug and play, containing one SainSmart Leonardo R3, one SainSmart IIC LCD1602. Features SainSmart Leonardo R3 Improved Version Board The SainSmart Leonardo is a microcontroller board based on the ATmega32u4 . It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. Microcontroller ATmega32u4 Operating Voltage 5V Input Voltage (recommended) 7-12V Input Voltage (limits) 6-20V Digital I/O Pins 20 PWM Channels 7 Analog Input Channels 12 DC Current per I/O Pin 40 mA DC Current for 3.3V Pin 50 mA Flash Memory 32 KB (ATmega32u4) of which 4 KB used by bootloader SRAM 2.5 KB (ATmega32u4) EEPROM 1 KB (ATmega32u4) Clock Speed 16 MHz SainSmart IIC/I2C/TWI 1602 Serial LCD Module This is another great Green backlight LCD display. As the pin resources of Arduino controller are limited, your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, with this I2C interface LCD module, you will be able to realize data display via only 2 wires. If you already has I2C devices in your project, this LCD module actually cost no more resources at all. It is fantastic for Arduino based project. I2C Address: 0x3F or 0x27 Backlight (Yellow character on Green background) Supply voltage: 5V Size: 82x35x18 mm Come with IIC interface, which can be connected by DuPont Line Package List: 1. 1x SainSmart Leonardo R3 board 2. 1X SainSmart IIC/I2C/TWI 1602 Serial LCD Module 3. 1X USB cable
