Proto Arduino - DIY Prototype Board
Arduino Nano or ATTiny85 Prototype Board
The Proto Arduino is a general-purpose prototyping platform. It is compatible with the Arduino Nano v3 or Digispark style ATTiny85 processors boards. Onboard features include a regulated power supply. Dedicated mounting provided for either an Arduino Nano or ATTiny85 processor board. The prototyping surface offers over 850 plated-through holes. Mounting for eight LEDs along with dropping resistors is also provided.
The Proto Arduino is a high-quality prototype board with solder masks on both sides of the board. Plated holes along with a high-contrast silk-screen labeling component positions. Board size is 3 3/4” x 5” (95mm x 127mm) ready to fit into standard size project cases.

Precautions When Assembling The Board
ATTiny85 Mounting Consideration
The Proto Arduino design allows for use with many manufacturers of ATTiny85 boards. Some designs have strayed from the original specifications. The pin spacing for the signal leads on the board can vary between various manufacturers. This variance can impede the installation into the proto board socket.
This can be overcome by slightly tipping the pins towards the bottom of the proto board. This solution has allowed us the flexibility to install all design variations in ATTiny85 boards. This should be done when you are soldering the connector to the PCB.
