From the project

Curso de Diseño de Circuitos Impresos de la Carrera de Especialización en Sistemas Embebidos

El Poncho "Procesador de Audio" es una placa de circuito impreso que se diseño para ser montada sobre la EDU-CIAA-NXP. Dicho pcb le brinda a la EDU-CIAA-NXP el hardware necesario para adquirir audio en modo estereo o en modo mono estereo, y además, el hardware necesario para generar el audio procesado en modo stereo o mono stereo. A su vez, se agrega hardware indicador de estado para el usuario y se agregan protecciones contra el mal uso del equipo.
