ICSJ002A ATmega32u4 Leonardo Compatible Arduino Leonardo to Good Use                     Overview   The Arduino Leonardo is a microcontroller board based on the ATmega32u4 (datasheet). 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. It also has other implications for the behavior of the board. Summary 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                                                                                                                      For more quantity,please contact us.     1) We accept PayPal payment ONLY.
