From the project
A home for a bunch of microcontroller projects which don't warrant their own repos.
microcontroller-projects ========================
A home for my microcontroller projects, including Stubby the Hexapod and others. It includes libraries for avr-gcc along with sample programs on how to use them, some KiCad modules, and the source code for a number of projects.
Some major projects include: Stubby the Hexapod (http://stubby.digitalcave.ca/stubby/) (Now extracted into its own repo at https://github.com/thebiguno/stubby) DrumMaster (http://drummaster.digitalcave.ca/drummaster/) * Chiindii (http://chiindii.digitalcave.ca/chiindii/)

Preamp: common questions
How big is the Preamp PCB?
The Preamp measures 15.2 × 10.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Preamp?
17 components, from 14 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 Preamp design files?
From the thebiguno/microcontroller-projects repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Preamp design in my own project?
The repository has no license, so all rights stay with thebiguno. Use it as a reference, and ask the author before reusing the design.
