El HAT IO Zero 32 para Raspberry Pi Zero es una placa de expansión digital de 32 canales diseñada para usarse en Raspberry Pi. La placa se basa en el expansor de E/S de 16 bits PCA9535 de NXP. Se incluyen un par de expansores PCA9535 en la placa que le permiten conectar hasta 32 entradas o salidas digitales a la Raspberry Pi.
El IO Zero 32 se alimenta a través del host Raspberry Pi usando el puerto GPIO y los pines extendidos en el conector GPIO le permiten apilar el IO Zero 32 junto con otras placas de expansión. El IO Zero 32 incluye un puerto de entrada de voltaje que se puede aislar de la Raspberry Pi a través de un puente de soldadura de aislamiento marcado como "Link" en la PCB para que pueda usar una fuente de alimentación de alta corriente separada para alimentar el IO Zero 32 reduciendo la carga en el Raspberry Pi.
