این ماژول از تراشه ISD20 برای ضبط و پخش صدا استفاده می کند. تمامی صداها در حافظه ای غیر فرار بر روی ماژول ذخیره شده و تا سالیان سال در آن باقی خواهد ماند. همچنین امکان ضبط و پاک کردن صدا تا 100000 مرتبه وجود دارد. محدوده زمانی که برای ضبط صدا می توان استفاده کرد، 8 تا 20 ثانیه می باشد.
به دلیل وجود یک آمپلی فایر داخلی، امکان راه اندازی یک اسپیکر 8 اهم 0.5 وات توسط این ماژول وجود دارد. یک میکروفون نیز بر روی برد تعبیه شده است.
