Radioconstructor `` Start-7245 '' (Programmable microcontroller).

Radio and electrical constructors, sets.Multifunctional devicesRadioconstructor "Start-7245" (programmable microcontroller) has been produced since the 1st quarter of 1990. RK "Start-7245" includes a completely finished board with a microcontroller of the K145VM1901 series and two printed circuit boards with a set of parts for assembling two options for output stages: a single-pole electronic relay module of the "key" type on a composite transistor (Darlington circuit) and a module of two bipolar electronic relay, now called "N-bridge". In addition, the kit includes a thick instruction and a set of diagrams, including a circuit of the microcontroller itself. The controller has a keyboard with a pair of switches ("run-programming" and "single-cycle"). with numbers and arrows, the direction and duration of movement in any of the four directions is set.The operation of the program is accompanied by the blinking and blinking of the LED.
