ATtiny85 USB Development Board

This board is one of the smallest Arduino-compatible development boards around with most of the features you expect from a microcontroller (Digital I/O, ADC, PWM, I2C etc.). Aside the ability to be used in standard microcontroller projects, it can also be programmed to act as any USB device such as mouse, keyboard, joystick etc., opening up the opportunity for many fun and interesting projects! The small size makes it perfect for embedding in your project, and the low-cost means you can leave it permanently in your old projects and just purchase another for your new project :-).
