Description
Iteaduino Tiny is a mini development board based on the Attiny85-20 master, which is cheap, compact, easy to use, and has low power consumption. The mainboard is a derivative board concerning digipack design, and it supports the use of specific Arduino IDE and uses Arduino syntax for programming which is quite convenient.
FEATURES
- Support for the Arduino IDE 1.0+ (Windows)
- Power via USB
- Built-in USB
- 4 I/O Pins
