AudioToy is a set of modules to complement an 8x8 CS42448-based Teensy 4.0 audio board, providing fully balanced, software gain-controlled input and output modules.
Fully balanced or unbalanced microphone, line and instrument inputs are supported and the output stages can drive 600 ohm loads at +8dBm. Only a 5V supply is required.
All hardware information is available for open access at https://github.com/palmerr23/AudioToy with full schematics, BoM, Gerbers and design notes provided.
An ESP32 provides WiFi connectivity for remote control.
