SoundMixer
About the SoundMixer PCB
SoundMixer is an open source PCB design by LeKoYa, published on GitHub under the MIT license. It is a 2-layer board measuring 30 × 30 mm, with 37 components from 7 distinct parts.
Other key parts include the XL-1010RGBC-WS2812B. By type, the board carries 25 ICs, 6 resistors, 4 capacitors, 1 connector and 1 switch.
It belongs with the displays & leds designs in this gallery.
From the project
A deej-powered Soundmixer for individual volume control with rotary encoders, leds, buttons and oled support
This is still an early version and rebuilding your own might become very tricky. I am actively working on a second version that will be easier to build and assemble.
The pcb was designed in kicad. I am still working on a version2 that features two pcbs stacked on top of each other, so the encoder does not stick out too far above the leds.
