Features:

• Bi-directional control for two brushed DC motor.    
• Support motor voltage ranges from 6VDC to 24VDC.  
• On board test button for manual control of motor.
• Every channel output built with LED indicator. 
• Maximum current up to 10A continuous (without heatsink at 25℃) and 30A peak (10 second).
• Current limiting at 30A.   
• Raspberry Pi compatible connector.    
• Solid state components provide faster response time.   
• Fully NMOS H-Bridge for better efficiency and no heat sink is required.   
• Speed control PWM frequency up to 20KHz (Actual output frequency is same as input frequency from Raspberry Pi).
• Support sign-magnitude PWM operation.   
• Support TTL PWM from microcontroller, not PWM from RC receiver.
• Dimension:67.5mm x 59mm
