README
README.mdSoundHive - V2.0
SoundHive is a low cost open source audio amplifier, designed to be stacked much like Arduino, the aim is to reduce electronic waste by utilizing existing speakers. It's too common for people to buy a new home theatre system and dispose of the old equiptment, which ends up directly in a landfill.
The reality is that most of the speakers made ~20 years ago are high quality wooden builds, that sound awesome and simply can't be replaced by their shiny new plastic childen.
Soundhive also increased modularity and customization. This allows the greater flexibility.
V2.0 is an evolution of the original project, which can be found here: https://github.com/Machine-Hum/SoundHive

Questions
How big is the Power PCB?
It measures 42.7 × 46.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Power use?
208 parts, built around the LMV358 and LM9036MX-5.0. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Power KiCad files?
From the o7-machinehum/SoundHive-V2.0 repository on GitHub, at the commit this page was made from: the board is ELEC/PowerBoard/Power.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power design in my own project?
Its repository states no licence, so its author keeps all rights: ask o7-machinehum before reusing the design.
