The modern development of brain-computer interfaces (BCI) technology is actively expanding the functionality of rehabilitation measures and opportunities to improve the standard of living for patients with movement disorders, so the problem of developing low-cost and small-sized devices for everyday use is becoming increasingly important. This article describes the stages of developing a biological signal registration unit for potential use in BCI, as well as assembly and adjustment of the circuit on a solderless and solderable breadboard. Analysis of this prototype was carried out with the help of laboratory equipment to estimate circuit characteristics. The results of the experimental study with a healthy volunteer to assess the performance of the prototype are obtained. The main problems encountered during the experimental study are identified and methods for solving them are proposed.
