    Works immediately after soldering input/output/power and plugging, nice sound (with mini speakers). Very small size (only a bit larger, than a thumb nail), so it can be placed anywhere in a speaker case.

    Очень хороший звук. Размеры платы небольшие, занимает минимум места в корпусе. Использую для мини-стерео-системы. Пока доволен.
