2804 Brushless DC Motor + Driver Board Knob Speed Control Kit
2804 Brushless DC Motor + Driver Board Knob Speed Control Kit
2804 Brushless DC Motor + Driver Board — Knob Speed Control Kit
Take full command of motor speed and direction with this ready-to-run 2804 Brushless DC Motor and Driver Board Kit. Designed for makers, engineers, and electronics enthusiasts, this set delivers smooth open-loop brushless motor control right out of the box — no Hall sensors required. Simply connect power, wire the UVW three-phase leads to the silk-screened terminals, and dial in your desired speed with the onboard knob.
Key Features
- Plug-and-Play Speed Control: Voltage-based speed regulation via a simple knob — no complex programming needed to get started.
- Forward & Reverse Control: Easily switch motor rotation direction for versatile application use.
- Wide Speed Range: Stable operation from 180 RPM up to 3,100 RPM for precise low- and high-speed applications.
- No Hall Sensor Required: Sensorless open-loop control keeps wiring simple and component count low.
- Smooth Startup: Low-speed debugging stability ensures gentle, reliable motor starts every time.
- Optional Encoder Upgrade: Choose the kit variant with the AS5600 magnetic encoder to connect to a microcontroller and read cumulative rotation angle and speed data via programming (example code included).
- Microcontroller Compatible: With the encoder option, interface directly with your MCU for closed-loop or data-logging projects.

Frequently Asked Questions
Q: Does the 2804 brushless DC motor driver board require Hall sensors?
A: No. This kit uses sensorless, open-loop control — no Hall sensors are needed. Simply connect the UVW three-phase leads according to the silk-screened markings on the driver board, connect your power supply, and use the knob to control speed.
Q: What is the operating voltage range for this brushless motor kit?
A: The recommended operating voltage is 12V DC, with a maximum of 20V (not to exceed the motor's rated maximum voltage). Current draw is under 1A under normal operating conditions.
Q: Can I read the motor's speed and rotation angle with this kit?
A: Yes — if you select the kit variant that includes the AS5600 magnetic encoder. Connect the encoder to your microcontroller, use the provided example code, and you can read out the cumulative rotation angle and real-time speed data through your development environment.
Q: What is the brushless motor's speed range?
A: The motor supports a speed range of 180 RPM to 3,100 RPM. Low-speed operation is stable and startup is smooth, making it suitable for a variety of DIY robotics, automation, and electronics projects.
Q: Is this kit suitable for torque-sensitive applications?
A: The driver board uses voltage-based speed control, which may result in some torque reduction at low speeds. For applications where precise torque control is critical, FOC (Field-Oriented Control) is recommended as an alternative control method.
