Project Aether
@shiva233

This board is a Bluetooth to PC audio bridge! It lets you connect devices such as consoles or phones to it via Bluetooth to transmit audio, and then the board sends the audio through to your PC headphones with a wired connection!! TLDR: It lets you pass audio through to your PC from external devices :D
