ATtiny85 8-Bit Microcontroller

From the manufacturer of the common ATmega328P found in many Arduinos, the 8-bit ATtiny85 is an eight-pin microcontroller. If you have a simple Arduino project and want to make it smaller in size, then the ATtiny85 is a great way to do so. You can use the Arduino IDE and another Arduino board to program this little guy. Specifications Voltage (VDD): 2.7-5.5V Program Memory: 8KB RAM: 512B EEPROM: 512B I/O Pins: Total I/O: 6 pins Analog Input: 4 pins Analog Output (PWM): 2 pins Timers: 2 Clock Speed: 1, 8, or 16MHz internal, or up to 20MHz with external crystal Pinout Arduino Related Pinout Resources Datasheet Tutorial: Programming ATtiny85 with Arduino UNO Expanding the ATtiny85's IO Capacity with Shift Registers Order 74HC595 8-Bit shift registers
