The ATtiny85 -based mini development board is similar to the Arduino but cheaper and smaller (of course a bit less powerful). With a whole host of shields to extend its functionality and the ability to use the familiar Arduino IDE, this ATTINY85 USB Development Board is a great way to jump into microcontroller electronics. ATtiny85-based microcontroller development board come with a USB interface. Coding is similar to Arduino, and it uses the familiar Arduino IDE for development. It has 6 ports with several functions. Depending on the programming (with Arduino IDE) can it have 6 digital I/O, 4 analogue inputs or 3 PWM outputs. It can be powered by a USB port or an external power supply of 6-35V DC.ATtiny85 Features:Support for the Arduino IDE 1.0 (OSX/Windows/Linux)Power via USB or External Source or 7-16 v to 5 v (automatic selection)The On – board, 150 ma 5 v RegulatorBuilt-in USB and serial was debugging)6 I/O Pins (2 inform the for USB only if your program actively communicates over USB, otherwise you can use all 6 even if you are programming via USB)8 k Flash Memory (about 6 k after bootloader)The I2C and SPI (vis USI)PWM on 3 pins (more possible with Software PWM)The ADC on 4 pinsThe Power LED and the Test/Status LEDsPackage Includes:1 x ATTINY85 Micro USB Development Board for Arduino
