A high-efficiency DC-DC step-down (buck) converter that accepts 6–24 V input and delivers a stable 5 V output at up to 16 A. With over 90% conversion efficiency at typical loads and output ripple below 20 mV, it provides clean, reliable power for demanding applications.
The module includes over-temperature protection (125 °C), output short-circuit protection, and a thermal pad on the back for soldering to a large copper area to improve heat dissipation during sustained high-current operation.
Key Features
- Wide Input Range – 6–24 V DC input, stable 5 V ±1% output
- 16 A Maximum Output – Plenty of current for motors, servos, and LEDs
- High Efficiency – Over 90% at 12 V input with 1–16 A load
- Low Ripple – Less than 20 mV output noise
- Built-In Protections – Over-temperature (125 °C) and short-circuit protection
- Thermal Pad – Solder to copper pour for enhanced heat dissipation
- Control Pins – EN (enable/disable), AGND (control ground), and PGOOD (power-good status)
Control Pins
- EN – Enable/disable output via microcontroller IO pin (use a 1 kΩ series resistor)
- AGND – Single ground point for microcontroller control
- PGOOD – Outputs 5 V when output is normal, 0 V during fault or short circuit

Jargon buster
Plain-language definitions for the technical terms used above.
- ESC
- An ESC, or electronic speed controller, is a driver commonly used to control brushless motors, especially in drones and RC vehicles. Comparing this board with a conventional ESC matters because FOC drivers can offer smoother low-speed control and more precise torque or position control.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
