Description

Arduino Leonardo with Headers (A000057)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

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; these are detailed on the Getting started with the Arduino Leonardo guide.

Not paper thin like most T-Shirts
Color: Light Khaki, Size: X-Large
These Cooney tshirts are really nice. Feel like 100% cotton and keep their shape and color. Size true to fit. Good value for the money. Love the mock neck style. Bot a couple one in white and one in black. Then went back and ordered 6 more various colors. Like the all.
