Programmable Audio Routing PCB Design
Budget: $30 – $250 USD
I'm looking for an experienced PCB designer to create a programmable audio routing PCB using an ESP32 microcontroller. The board will feature:
- 6 buttons in a straight line to control presets.
- 6 LEDs to display the current preset.
- 4 XLR mic input/output sets.
- 4 speaker input/output sets via terminal blocks.
- High-power handling for speaker inputs/outputs (50-100W, 4-8Ω).
- 12V DC power via barrel jack.
- USB interface for programming the ESP32.
The microcontroller needs to turn mics and/or speakers on or off, depending on the preset corresponding to whatever preset button has been pressed. I need to be able to program the ESP32 to set up the presets that I want.
Ideal skills and experience:
- PCB design expertise.
- Experience with ESP32 and microcontroller programming.
- Knowledge of audio routing and signal handling.
