The advantages of the solid state photodiodes, Hamamatsu S12572-100P type, are the reduced occupied volume, the small operation voltage, the high amplification factor, the magnetic field effects insensibleness, and other desirable physical characteristics against the conventional big vacuum-phototubes technical features. Here are the studies on a feeding, reading out, and digitizing one channel electronic board for the S12572-100P Hamamatsu photodiode. The applications are very general in cosmic ray detectors, high energy particle detectors, and radiation detection in general. The results are based on a study of 15 electronic boards (ten feeding and reading out boards and five digitizing boards) planned, designed, constructed, and tested for these purposes. The waveband of operation varies within a range from 100 Hz to 1 MHz; the ratio of outgoing signal to incoming signal (attenuation factor) is about 82% between 100 Hz-10 kHz, is 72% between 10 kHz-1 MHz, and is 78% between 100 Hz-1 MHz; phase shifts between the incoming and outgoing signals are close to zero degrees for all frequencies, and occasionally have values different from zero degrees; digitizing efficiency is 99.99%; signal transit time is about 738.08±62.38 ps; and digitizing time is about 2.88±0.15 ns. The electronic board one channel ensemble works as it was planned. More technical details and physical characteristics are described in this paper.
