JUYI Tech JYQD-YL02D Dual BLDC Motor Driver Board 12V-36V 15A with energy recovery braking, PWM/analog speed control

The JYQD-YL02D is a high-performance, compact dual-channel Brushless DC (BLDC) motor driver board engineered by Shanghai Juyi Electronic Technology Development Co., Ltd (JUYI Tech), a premier BLDC motor driver manufacturer in China. Operating across a wide voltage range of 12V to 36V DC with a continuous working current of 15A per channel, the JYQD-YL02D is designed for 3-phase sensorless/sensored brushless motors with a 120-degree Hall sensor configuration.

Featuring advanced reactive linear braking with energy recovery, precise PWM or Analog voltage speed control, and bidirectional control (Forward/Reverse), this dual BLDC motor driver delivers high efficiency, robust system stability, and a compact layout (100mm × 59mm) for industrial and commercial mobility platforms.

Note:Safety start: if you use a knob style potentiometer to adjust the speed, if the potentiometer not rest to 0 before stop,the motor will direct start according to the last operation,it not safe,so safety start function will automatic reset to 0 to avoid the motor start directly in next power on.

• Dual-Channel High-Efficiency Control: Eliminates the need for two separate driver boards in two-wheel or differential drive systems, reducing footprint and wiring complexity.

• Energy Recovery Braking System: The built-in reactive linear braking system generates energy back during deceleration, extending overall battery endurance for electric mobility devices.

• Versatile Interface Compatibility: Easily interfaces with Microcontrollers (MCU), Single-Chip Computers, PLCs, or RC receivers via 2.0mm pitch control terminals.

• Built-in Circuit Protection & Safe Start: Integrated safety mechanisms prevent motor surge or unexpected movement during power-up or speed setting reset.

The JYQD-YL02D dual BLDC controller is widely integrated into global B2B OEM/ODM projects:

• Electric Personal Mobility: Electric wheelchairs, dual-drive electric scooters, self-balancing boards, and electric skateboards.

• Autonomous & Mobile Robotics (AGV / AMR): Warehouse logistics AGVs, service robots, differential-steering robotic chassis.

• Smart Hardware & RC Platforms: Heavy-duty remote-controlled vehicles, conveyor drive units, and specialized hub motor applications.

1.  Control Port (Left)2.0 hole spacing

• 5V--Driver board internal output voltage,can provide external current<300MA.
• 2EL--Brake control port,reactive and linear brake with energy recovery function,analog voltage brake 0-5V.In the case of constant speed+, the higher the braking voltage, the greater the braking force 0-100%.
