The Adafruit Trinket 5V mini-microcontroller is a tiny (27 x 15mm) Arduino compatible processor board which is programmable via its micro-USB socket. Its ATtiny85 processor has 8k bytes of flash (programme) memory, 512 bytes of SRAM (static RAM) and 512 bytes EEPROM and runs at up to 16MHz. The board is capable of outputting 150mA and has an ultra-low drop-out regulator which will switch between USB and battery supply automatically. Adafruit provide a free tutorial and example code to get you started, imagine driving 150 NeoPixels with such a dinky board. Supplied as a fully assembled board plus 2 x 5-pin strips of 0.1in. male header pins for you to solder on as required.

To get such a tiny form-factor a few compromises had to be made. It does not contain an Arduino serial port connection for debugging and some computer USB V3 ports will not recognize the Trinket's bootloader, but USB V2 ports will.
