This compact three-phase brushless DC motor is built for advanced motion control projects where smooth torque, low noise and precise feedback matter. It runs at a rated 12V and combines a 2804 BLDC motor with a built-in AS5600 magnetic encoder for closed-loop control.
The integrated encoder provides 12-bit angular position feedback directly on the motor, with I2C, PWM and analogue output options. That makes it well suited to Field-Oriented Control (FOC) setups for position, speed and torque control without having to mount a separate encoder.
The motor uses a CNC-machined aluminium housing with a black anodised finish, an outer rotor with NdFeB magnets, and a hollow shaft design. It is designed to work with the SimpleFOC library and common development boards such as Arduino, ESP32 and Raspberry Pi when paired with a compatible motor driver.
Included in the pack are the 2804 3-phase brushless DC motor with encoder, an MX1.25-4P to DuPont cable, and a 3-pin motor cable.

Jargon buster
Plain-language definitions for the technical terms used above.
- BLDC
- BLDC stands for brushless DC motor, a motor type that uses electronic switching instead of brushes to make it spin. It matters because BLDC motors need a suitable driver and control method, especially when you want smooth low-speed movement or precise positioning.
- closed-loop control
- Closed-loop control means the system uses feedback, such as motor position or speed, to adjust its output automatically. This matters because it can keep a motor moving accurately even when the load changes, unlike simple open-loop control.
- encoder
- A device attached to a motor or shaft that reports movement, such as rotation steps or position. In a pump system, an encoder can help measure or control how much the motor has turned, which affects how repeatable the watering amount can be.
- ESP32
- ESP32 is a family of microcontroller modules with built-in wireless features such as Bluetooth and WiFi. Knowing this product uses an ESP32-based module helps explain how it provides wireless serial communication and firmware update features.
- Field-Oriented Control (FOC)
- Field-Oriented Control is a motor-control method that carefully controls the magnetic fields inside a brushless motor for smoother and more precise motion. It matters for projects such as robotics, gimbals, and haptics where quiet operation, low-speed control, or accurate torque control is important.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- Matter
- A smart home connectivity standard designed to let devices work across different ecosystems. It matters if you want a project to integrate more easily with platforms such as Apple Home, Google Home, or other Matter-compatible systems.
- motor driver
- An electronic circuit that lets a low-power controller switch and control a motor that needs more current than the controller pins can safely provide. Checking motor driver support matters because pumps and motors usually cannot be connected directly to a microcontroller output.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- Torque
- A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
