ATtiny/Little jumper
Little jumper
Lets break out the ATtiny85 and create an Arduino alike development board.
Proto 0.01 Work on the idea with Fritzing
- A dipsocket with breakout headers.
- ICSP headers.
- Power line with jumper to switch on and off.
- Disable jumper for the reset line (so we can plug D10 from the Arduino as we use that as ISP).
Proto 0.02 Testing the idea with a functional board

Using an Arduino Nano as ISP on the ICSP headers
Proto 0.03
For a cleaner result it helps to add more traces on the board. With the other (cheaper) perfboard it became a problem when the soldering pads came off (both during soldering causing tension on connections and placing jumpers etc.)
The new board has trough hole pads enabling better mechanical characteristics (it's a part from a Arduino proteshield cut in pieces). It's easier to create traces and looks cleaner.
- A reset button is added to the board.
- Male headers are replaced for female so a shield can be attached later on.
