Features

• ATMEL ATTiny85 Microprocessor (or compatible 8-pin part)
• Arduino Compatible (works with Arduino bootloader and Arduino IDE)
• Prototyping area with power/ground connections
• Brings out all 5 I/O and reset lines to grid columns
• Laid out like a breadboard with vertically connected traces.
• Power and Ground horizontal connections though all columns
• Labeled (with letters/numbers) for easy documentation
• H1 - Install jumper to select regulator or remove for ISP +5V
• H2 - 6-pin ISP Download Header
• 5V Power Regulator with generous area under the regulator for heat dissipation
• 2.1mm Connector for AC/DC adapter 7-9V input
• (4) 4-40 or M3 screw holes for solid mounting
• 49x49 mm board

Why did you make it?

We love Arduinos and breadboarding but we often end up with projects which are really too small to waste an entire Arduino. We also wanted some way to breadboard our designs with an ATTiny85 part. Often times we just want one or two boards and find it hard to justify a new board spin.

A big frustration that we have with the Arduino is the lack of proper mounting holes. We think that boards should have mounting holes even if it costs a little extra for the PCB. And the mounting holes should take common hardware like #4-40 or M3 screws. Stuff we can buy at our local hardware store.

So we designed the TinyGrid85.

Here's a project we built using TinyGrid85.

Ordering Options

• Bare board - just the board, no parts. Bare boards are electrically tested by our manufacturer.
• Assembled board, board with everything installed but no GVS connector. The best option if you want to put a lot of stuff in the prototyping area.
• Assembled board with GVS connectors. A great way to easily hook up external three pin (GVS) devices.
• Assembled board without DC power regulator or jack. A simple and low-cost way to have an ISP programmer for 8-pin ATTiny parts. You can add the rest later if you want/need it.
