ATTiny88 Breakout Board: common questions

What microcontroller does the ATTiny88 Breakout Board use?

The ATTiny88 Breakout Board is built around the ATtiny88, from the AVR/Arduino family.

How big is the ATTiny88 Breakout Board?

The ATTiny88 Breakout Board measures 22.9 × 48.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ATTiny88 Breakout Board?

12 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the ATTiny88 Breakout Board design files?

From the mail4johnv/ATTiny88_Breakout_Board repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ATTiny88 Breakout Board design in my own project?

Yes, under the terms of its MPL-2.0 license, which mail4johnv chose for the repository.

Can I test firmware for the ATTiny88 Breakout Board without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
