Аnnotation: The results of development of the SM-3MU seismic module, which was started in 2015, are described. The module is close to SM-3 in terms of their characteristics. The module operates in the mode of a velocimeter with an electronic amplifier in the frequency range 0.5-40 Hz with a resolution of 10
