ATtiny Breakout/Programmer

Introducing the eeZee Tiny

To make it easier to prototype ATtiny-based circuits like my lost model alarm I made a breakout / programmer board for ATtiny13 pin-compatible chips. I call it the eeZee Tiny. It's a surface mount version of an existing open source project.

(The list of compatible chips includes the ATtiny11, ATtiny12, ATtiny13, ATtiny13A, ATtiny25, ATtiny45, ATtiny85)

The board has a 6-pin AVRISP header so I don't have to keep looking up pinouts, a reset switch and breadboard friendly header pins. Supply power to pins 4 and 8 and you're set.

I can either use the board to prototype the next project or embed them in projects permanently.

I made a few extras in hopes that it'll help out others. They're on sale at Tindie at the moment and for Cyber Monday you can use coupon code 8F7CD17 to get 25% off the regular price.

Features:

• Works with ATtiny13,13A, ATtiny25,45,85, ATtiny11, ATtiny12
• Tiny 1-square-inch board
• Perfect for breadboarding
• 0.1uF and 10uF filtering capacitors pre-soldered
• Compact AVRISP connector for easy programming
• All 8 pins exposed for breadboarding
• Reset switch and pull-up resistor included

Here are the Eagle files and example code so you can make your own. I had my boards done by oshpark.com and they turned out great as always.

Parts list includes a standard 6mm square tactile switch with 4 pins, one 0603 0.1uF ceramic cap, a 1206 10uF tantalum, a 0603 1K resistor, an 8PDIP socket, a 2x3 pin header, and a 1x8 (or two 1x4) pin header.
