Кораци инсталације:

Identify the input and output terminals on the module.
Connect your DC power source (e.g., battery, power adapter) to the ИН+ и ИН- terminals. Ensure the input voltagе је унутар наведеног опсега од 4.75В до 23В.
Connect your load (the device requiring power) to the ОУТ+ и ОУТ- терминали.
Before applying power, double-check all connections for correct polarity and secure contact.

4. Упутство за употребу

Излазни волtage of the Mini 360 module is adjustable using the onboard potentiometer.

With the input power connected and the load disconnected, apply power to the module.
Користите мултиметар да измерите запреминуtagе преко ОУТ+ и ОУТ- терминали.
Carefully turn the small screw on the potentiometer (the small metallic component with a screw slot) using a precision screwdriver. Turning clockwise typically increases the voltage, while turning counter-clockwise decreases it.
Adjust the potentiometer until the desired output voltage (between 1.0V and 17V) is achieved.
Једном жељени волtage is set, disconnect the input power, then connect your load to the output terminals. Reapply input power.
Напомена: Do not exceed the maximum output current of 3A, and avoid prolonged operation above 1.8A to ensure module longevity. Ensure the input voltage is always higher than the desired output voltage for proper step-down operation.

5. Одржавање

The Mini 360 module is a low-maintenance electronic component. Follow these guidelines to ensure optimal performance and longevity:

Одржавати уредним одржавати чистим: Ensure the module is free from dust, dirt, and moisture. Use a soft, dry brush or compressed air for cleaning if necessary.
Услови животне средине: Operate the module within its specified temperature range. Avoid extreme heat, cold, or high humidity.
Избегавајте преоптерећење: Do not draw more current than the module's rated capacity (1.8A continuous, 3A peak). Overloading can lead to overheating and permanent damage.
Сигурне везе: Periodically check that all input and output connections are secure and free from corrosion.
физичка заштита: Protect the module from physical impact or bending, which could damage the PCB or components.

КСНУМКС. Решавање проблема

Проблем	Могући узрок	Решење
Но оутпут волtage	Нема улазне снаге. Incorrect input polarity. Инпут волtagе прениско или превисоко. Module damaged.	Verify input power supply is active. Check input wiring for correct polarity (IN+ to positive, IN- to negative). Осигурајте улазну волtagе је између 4.75В и 23В. Replace module if damaged.
Оутпут волtage is incorrect or unstable	Potentiometer not adjusted correctly. Load drawing too much current. Инпут волtage fluctuating. Оутпут волtage set higher than input (not possible for buck converter).	Adjust potentiometer carefully with a multimeter connected to the output. Reduce load current or use a module with higher current rating. Ensure stable input power supply. Провери излазни обимtage is always less than input voltage.
Прегревање модула	Excessive output current. Недовољна вентилација. Ларге волtage difference between input and output at high current.	Смањите струју оптерећења. Ensure adequate airflow around the module. Consider using a heat sink if operating at higher currents or larger voltagе капи.
