SimpleFOCmini Brushless DC Motor Driver Board

The SimpleFOCmini Brushless DC Motor Driver Board is a compact, high-performance module designed for precise Field-Oriented Control of BLDC motors. Delivering closed-loop position, speed, and torque management across an 8-30V input range, it is an ideal solution for students, makers, and engineers developing robotics, camera gimbals, and mechatronics.

Compact design and robust power

Measuring just 26 x 21.5mm, this driver accepts an input voltage range of 8V to 30V DC and supplies up to 2.5A peak current per phase. It features onboard power reverse polarity protection to safeguard circuitry in space-constrained builds.

Smooth low-speed FOC performance

Unlike standard electronic speed controllers that struggle with low-speed stability, the integrated FOC algorithm maintains smooth and steady operation from a complete standstill to maximum RPM. This enables fluid acceleration and accurate control at any rotational speed.

Versatile closed-loop control modes

The board supports three distinct closed-loop operating modes: torque control for force-feedback systems, constant speed control under variable loads, and high-accuracy position control for robotic joints and actuators.

Quiet sinusoidal commutation

Utilising sinusoidal drive waves instead of standard high-frequency square waves, the driver significantly reduces acoustic noise and mechanical vibration. This makes it ideal for noise-sensitive setups such as camera stabilizers and precision laboratory equipment.

Broad microcontroller and library integration

With native 3.3V and 5V logic support, the board interfaces directly with Arduino, ESP32, and Raspberry Pi platforms. It is fully supported by the open-source SimpleFOC library, offering ready-to-use control algorithms and code examples.
