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.\u003c\/p\u003e \u003cp\u003e\u003cimg style=\"display: block; margin-left: auto; margin-right: auto;\" src=\"http:\/\/www.selloutsoon.com\/albums\/SKU\/20\/20-011\/20-011-D04\/20-011-D04\/07.JPG\" alt=\"\" width=\"650\" height=\"650\"\u003e\u003c\/p\u003e \u003ctable border=\"1\" cellspacing=\"0\" cellpadding=\"0\"\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e\u003cstrong\u003eMicrocontroller\u003c\/strong\u003e\u003cstrong\u003e \u003c\/strong\u003e\u003c\/p\u003e \u003c\/td\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e\u003cstrong\u003eATmega32u4\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e\u003cstrong\u003eOperating Voltage\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e \u003c\/td\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e5V\u003c\/p\u003e \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e\u003cstrong\u003eInput Voltage (recommended)\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e \u003c\/td\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e7-12V\u003c\/p\u003e \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e\u003cstrong\u003eInput Voltage (limits)\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e \u003c\/td\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e6-20V\u003c\/p\u003e \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e\u003cstrong\u003eDigital I\/O Pins\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e \u003c\/td\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e20\u003c\/p\u003e \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e\u003cstrong\u003ePWM Channels\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e \u003c\/td\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e7\u003c\/p\u003e \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e\u003cstrong\u003eAnalog Input Channels\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e \u003c\/td\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e12\u003c\/p\u003e \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e\u003cstrong\u003eDC Current per I\/O Pin\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e \u003c\/td\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e40 mA\u003c\/p\u003e \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e\u003cstrong\u003eDC Current for 3.3V Pin\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e \u003c\/td\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e50 mA\u003c\/p\u003e \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e\u003cstrong\u003eFlash Memory\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e \u003c\/td\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e32 KB (ATmega32u4) of which 4 KB used by bootloader\u003c\/p\u003e \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e\u003cstrong\u003eSRAM\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e \u003c\/td\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e2.5 KB (ATmega32u4)\u003c\/p\u003e \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e\u003cstrong\u003eEEPROM\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e \u003c\/td\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e1 KB (ATmega32u4)\u003c\/p\u003e \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e\u003cstrong\u003eClock Speed\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e \u003c\/td\u003e \u003ctd valign=\"top\"\u003e \u003cp\u003e16 MHz\u003c\/p\u003e \u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003cp\u003e\u003cstrong\u003eSainSmart IIC\/I2C\/TWI 1602 Serial LCD Module \u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThis 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.
