{"title":"Crowduino Leonardo","handle":"crowduino-leonardo","url":"/products/crowduino-leonardo","description":"The Crowduino Leonardo is a microcontroller board that completely compatible with the Arduino Leonardo. It is 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.The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.Features\nMicrocontroller: ATmega32u4\nT Working Frequency: 16MHz\nDigital I/O Pins: 20\nPWM Channels:7\nDC Current per I/O Pin 40Ma\nDC Current for 3.3V Pin: 50Ma\nFlash Memory: 32KB of which 4KB used by bootloader\nSRAM:2.5KB\nEEPROM: 32KB\nPower Supply: USB 5V or External Power 7~12V\nI/O Logic:3.3V/5V\nPackage list\nCrowduino Leonardo board x1\nMicro USB Cable X 1\nWiki & External linksWikiCrowduino Leonardo v1.01 eagle files","vendor":"Elecrow","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4073,"title":"Default Title","sku":"EC-ACA32U4CL","price":18.29,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
