ATTINY85-20 DIP

The ATtiny85 can be used to create small and compact circuits. The ATtiny85 can be programmed by a microcontroller, for example an Arduino Uno as ISP or with an USBasp AVR Programmer.

While the ATtiny85 has only 6 functional pins, it is still quite powerful. With (software) I2C, SPI, UART or default input/output a lot can be achieved. (Especially when multiple I2C devices are used).

The ATtiny85 can run on the internal 8MHZ oscillator which is more than enough for most applications.
