This was a little no frills breakout board I designed for Attiny 8 pin chips, minimal components but I had a few requirements that I wanted to meet.
1. ISP connector on board
2. Through hole only components, no SMT
3. ALl I/O pins brought out to headers
4. Seperate headers for Vcc and GND
We put in an order at OSHPark and received 3 boards, here is a picture of one of our boards populated which is running the LED flashing example
The schematic is underneath, its fairly basic
