ATtinyX5

The ATtiny25, ATtiny45 and ATtiny85 (and ATtiny13a) are the smallest AVR chips and they are all pin compatible. It is an easy and inexpensive way to get started. I created a basic breakout board and some shields to demonstrate how to program these small, but powerful chips.

ATtinyX5 Breakout Board

board

Breakout board for ATtiny25, ATtiny45 and ATtiny85 (and ATtiny13a). It has a 6-pin ISP header, all the data pins are lined-up for easy usage, reset button, and JST power. You can use a bridge to put a resistor on each data pin (0-4).

ATtinyX5 Shields

bridge

The bridge connects the breakout board with the actually project. It puts a resistor on each data pin.

pov

Similar to the original MiniPOV - 5 LEDs connected to all the data pins. Great to learn about programming and just debugging of some code. Needs a board and a bridge.

led20

20 LEDs Charlieplexed. Needs a board and a bridge.

hex

19 LEDs Charlieplexed. Needs a board and a bridge.

TV-B-Gone Shield

This simple shield turn the board into a full-fledged TV-B-Gone.
