3.3v 8m Arduino Compatible Lilypad Usb Atmega32u4 Development Board

3.3V 8M Arduino Compatible LilyPad USB ATmega32U4 Development Board Feature: A microcontroller board based on the ATmega32u4 9 digital input/output pins (of which 4 can be used as PWM outputs and 4 as analog inputs) An 8 MHz resonator A micro USB connection A JST connector for a 3.7V LiPo battery A reset button Contains everything needed to support the microcontroller Simply connect it to a computer with a USB cable or power it with a battery to get started ATmega32u4 has built-in USB communication, eliminating the need for a separate USB-to-serial adapter. Which allows the LilyPad USB to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port. Specification: Microcontroller: ATmega32u4 Operating voltage: 3.3V Input voltage: 3.8V to 5V Digital I/O pins: 9 PWM channels: 4 Analog input channels: 4 DC current per I/O pin: 40mA Flash memory: 32KB (ATmega32u4) of which 4KB used by bootloader SRAM: 2.5KB (ATmega32u4) EEPROM: 1KB (ATmega32u4) Clock speed: 8MHz Package included: 1 x Arduino compatible LilyPad USB
