Attiny85 Digispark Development Board
Shrink your Arduino projects right down to a tiny board. Fully compatible with most Arduino code, the ATTiny is the smallest possible Arduino, due to its size there are only 6 IO pins available (2 are shared with USB)
The ATTiny only has 8Kb of memory and 3 PWM pins
Note
This has 5v logic, so make sure a logic leveller is used when interfacing with 3.3v microchips or sensors
Featuring;
Atmel ATTiny85 microcontroller
6 Digital Input/Outputs (2 are used for USB only if your program actively communicates over USB, otherwise you can use all 6 even if you are programming via USB)
8k Flash Memory (about 6k after bootloader)
On Board 100mA 5 Regulator
