The Nema 17 stepper motor boasts a compact and robust design, with an end face size measuring 1.7 inches by 1.7 inches. Known for its versatility, it is available in both single-shaft and dual-shaft configurations, making it suitable for a variety of applications. This motor operates with a precise step angle of 1.8°, translating to an impressive 200 steps per revolution, which allows for smooth and accurate movements.

Each phase of the NEMA 17 motor draws 1.2 A at 4 V, delivering a reliable holding torque of 3.2 kg-cm. This characteristic makes it ideal for demanding tasks where consistent positioning is essential. The Nema 17 stepper motor is widely utilized in numerous applications, including 3D printers, CNC machines, and laser cutters, where its precision and torque capabilities can significantly enhance performance and efficiency.

Solar panels are a clean and ecological source of electricity. Obtaining this energy, however, poses several challenges for device designers. The amount of energy produced by the panel is strongly dependent on the angle of incidence and the intensity of the light falling on the surface of the cells. This, in turn, leads to unstable power supply parameters at the output, as even shading a small part of the panel may drastically reduce the efficiency

The optimal solution to the above-mentioned problems is the use of a set consisting of a solar panel, a battery and a charge controller. Such a set allows to ensure constant parameters of power supply to receivers and also to store energy produced excessively for later use

The SCC-30A-PWM-LCD solar charge controller allows you to connect panels both in series and in parallel – remembering not to exceed the permissible values of current and voltage at the input of the device. Due to the operating characteristics of the PWM controllers, it should be remembered that when the panels are connected in series, the rated voltage at the output for charging the battery is 24V.
