PCB Assembly Variants for KiCad
by robertklee
Audio Effects Circuit Design & Embedded Systems (STM32F407 microcontroller) Design Project. Goal: with an analog audio input, pitch shift or add echo effect and output to a speaker. Circuit: designed AC level shifting circuit, active bandpass filter, LED matrix display and DAC quantization error smoothing in KiCad; manufactured as a printed circuit board; soldered components and tested PCB. Embedded Systems: FFT to extract frequency domain; NVIC with timer-raised interrupts to service analog sampling, button debouncing, and image display on LED matrix; memory and clock cycle optimizations
