simplified audio circuit
$30-250 USD
Πληρώθηκε κατά την παράδοση
I need a PCB schematic and gerber file for a simple audio player that supports LED animations during audio playback. The end goal is to generate a low cost PCB for manufacture. The circuit will play .wav files from an external sd card connection with single button press interface. The final circuit should contain whatever amplifiers, filters or converters needed to play on one small 8ohm 1 watt or less speaker. The circuit should also support seven WS2812B leds for simple light animations during music playback. Don't care whether SPI or I2C is used as long as there is no perceivable playback lag. I already prototyped this circuit using an Arduino for proof of concept, but I need a more viable, low cost, small board (e.g., 38mm x 30mm) for the end design.

Arduino Nano circuit must be replaced into a new PCB with required input and output filtering. If you dont need DSP, then its much easier. I would win projects for high rates, this is why I am cheap. Relevant Skills Περισσότερα
