Controller PWM


Recommended Posts

Din pacate nu pot cauta PWM pe forum pentru ca regula spune ca se pot cauta minim 4 caractere.Vreau sa controlez cateva ventilatoare pwm (din acelea folosibile intr-o carcasa ATX), nu stiu exact cate, dar in jur de 8. Controlul il voi face dintr-un raspberrypi dar acesta are un singur port pwm hardware si eu as vrea sa am control individual pentru ventilatoare. Din ce am citit exista controllere PWM cu interfata I2C de exemplu, si chiar am gasit cateva modele, dar ele nu se regasesc si in oferta magazinelor din tara. Aveti cunostinta despre un astfel de cip care s-ar gasi si pe la noi? (Nu conteaza interfata dar sa aiba mai multe canale).Merci
