ATmega32u4 LEONARDO DEVELOPMENT BOARD

Description

This board is a microcontroller board based on the ATmega32u4 (Arduino® Compatible leonardo). 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; connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

This product is a replacement of: VMA103
