  Ultra Fast Silicon Detectors (UFSD) are sensors optimized for timing
measurements employing a thin multiplication layer to increase the output
signal. A multipurpose read-out board hosting a low-cost, low-power fast
amplifier was designed at the University of Kansas and tested at the European
Organization for Nuclear Research (CERN) using a 180 GeV pion beam. The
amplifier has been designed to read out a wide range of detectors and it was
optimized in this test for the UFSD output signal. In this paper we report the
results of the experimental tests using 50 $\rm{\mu m}$ thick UFSD with a
sensitive area of 1.4 $\rm{mm^2}$. A timing precision below 30 ps was achieved.
