Foundation design files

The KiCad project lives in the odeliy/noise-reap repository on GitHub; these links point at the commit this page was built from.

Foundation: common questions

What microcontroller does the Foundation use?

The Foundation is built around the ATTINY45, from the AVR/Arduino family.

How big is the Foundation PCB?

The Foundation measures 48 × 110 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Foundation?

123 components, from 43 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Foundation design files?

From the odeliy/noise-reap repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Foundation design in my own project?

The repository has no license, so all rights stay with odeliy. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Foundation 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.
