Mini360 DC-DC Buck Converter Module — 2A, Adjustable 1V–17V Step-Down, 2pcs
The Mini360 is an ultra-compact synchronous DC-DC step-down (buck) converter module based on the MP2307 IC, providing adjustable output voltage from 1V to 17V at up to 2A continuous current from an input of 4.75V to 23V. The miniature footprint (17×11mm) makes it ideal for space-constrained applications including RC aircraft, FPV drones, Arduino power regulation, and embedded system power supply design. Output voltage is set by a small onboard trimmer potentiometer. Supplied as a 2-piece pack.

Typical Applications
- RC Aircraft & FPV Drones: Step down 2S/3S/4S LiPo voltage to 5V for flight controller, receiver, and video transmitter power supply in RC aircraft and FPV drone builds
- Arduino Power Regulation: Provide regulated 5V or 3.3V to Arduino boards from higher-voltage battery packs or unregulated power supplies
- Automotive 12V to 5V: Step down 12V vehicle power to 5V for USB chargers, dashcam power, and in-vehicle electronics
- LED Driver: Adjustable constant-voltage LED driver for single-colour LED strips and LED arrays requiring precise voltage control
- Embedded System Power: Compact power regulation for IoT devices, sensor nodes, and embedded systems requiring 3.3V or 5V from a higher-voltage source
- DIY Power Supply: Core regulation module for custom bench power supplies and battery-powered project enclosures
How to Adjust Output Voltage
- Connect input voltage (4.75–23V) to VIN+ and GND
- Connect a multimeter to VOUT+ and GND
- Use a small flathead screwdriver to turn the trimmer potentiometer clockwise to increase output voltage, counter-clockwise to decrease
- Set to desired output voltage before connecting the load
- Do not exceed 17V output or 2A continuous load current
FAQ
Q: Can the Mini360 output more than the input voltage?
A: No. This is a step-down (buck) converter only — output voltage must always be lower than input voltage. For step-up (boost) conversion, use an MT3608 or XL6009 boost converter module.
Q: Does the Mini360 need a heatsink?
A: At loads below 1A, no heatsink is required. At 1.5–2A continuous load, the module will run warm — ensure adequate airflow. A small heatsink on the MP2307 IC is recommended for sustained 2A operation in enclosed spaces.
