What is a Buck Converter?
A buck converter (step-down converter) is a DC-DC power supply circuit that efficiently reduces an input voltage to a lower, regulated output voltage. Unlike linear regulators, buck converters waste very little energy as heat, making them the go-to choice for battery-powered devices, IoT modules, microcontroller power supplies, and DIY electronics projects.

Frequently Asked Questions
Q: What is the maximum output current of the Mini360 buck converter module?
A: The Mini360 DC-DC buck converter is typically rated for up to 1A continuous output current (with adequate airflow). For higher current applications, ensure proper heat dissipation or consider a larger module. Always check your load requirements before use.
Q: Can I use the Mini360 to power an Arduino or Raspberry Pi?
A: Yes! The Mini360 step-down module is a popular choice for powering Arduino boards (5V) and Raspberry Pi units (5V) from higher voltage sources such as LiPo batteries (7.4V–12V). Simply adjust the output voltage using the onboard trimmer potentiometer before connecting your load.
Q: How do I adjust the output voltage on the Mini360 module?
A: The output voltage is adjusted using the small trimmer potentiometer on the module. Connect your input voltage, then use a small flathead screwdriver to rotate the potentiometer while monitoring the output with a multimeter until you reach your desired voltage (between 1V and 17V).
Q: Is the Mini360 buck converter suitable for outdoor or harsh environments?
A: With an operating temperature range of -40°C to +85°C, the Mini360 is well-suited for a wide range of environments. For outdoor use, consider adding conformal coating to protect against moisture and dust.
