Attiny 5 Version 1

Attiny 5 Version 1 designed as a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. the ATtiny5 achieves throughputs close to 1 MIPS per MHz, by executing powerful instructions in a single clock cycle.  This helps the system designer to optimize the device for power consumption versus processing speed. This development board features a 20MHz, AVR 8-bit microcontroller with 8 KB flash, 512 bytes of RAM. It comes with  5 GPIOs, 4 ADCs, 2 PWMs, 1 SPI, and 1 I2C. Moreover, this board fully compatible with Arduino and it directly programmed via USB without needing any other programmer. As there is only a total of 6 pins, it is not possible to get everything at the same time. Attiny 5 Version 1 differs from its upgraded version 2, as it connected using a cable.
