description: The object of research is the photoelectronic multiplier FEU-85 and the MAX668EUB microcontroller. The aim of the work is to develop a compact photoelectronic multiplier unit on a microcontroller for detecting weak light pulsations. As a result of the study, the properties and circuitry of the photoelectronic multiplier were considered, the circuits of the high-voltage power supply and the preamp of the FEU-85 were modeled. In the course of the work, a systematic approach and computer modeling of the block components were used. During the work, the FEU-85 photoelectronic multiplier and the MAX668EUB microcontroller were used. Their properties and main characteristics were described. A 1250 V high-voltage power supply has been developed. This voltage gives an anode sensitivity of 100 A/lm and a dark current of 10-7 A. During the simulation, the Micro-Cap 12 microcontroller was replaced by a pulse voltage source of 5 V with a frequency of 100 kHz. We received a feedback voltage of 1.25 V, which corresponds to the threshold value in the documentation. The EasyEDA is assembled with the participation of microcontroller. A pre-amplifier of the FEU-85 photoelectronic multiplier based on op-amp has also been developed. When modeling in Micro-Cap 12, a pulsed current source of -50 ÂµA is taken for the current from the FEU anode. A sinusoidal signal oscillating near 3.5 V is received at the output of the preamp. EasyEDA was modeled with the FEU-85 in accordance with the photoelectronic multiplier documentation. The resulting photomultiplier unit can be used in medicine, spectrometry and the detection of single light quanta. Open educational resources and software for information retrieval and analysis were used. Computer-aided design tools Micro-Cap 12 and EasyEDA were used. Micro-Cap 12 and EasyEDA software are used.
