Product User’s Manual – HAT-MDD10

1. INTRODUCTION/OVERVIEW

HAT-MDD10 is designed to drive two high current brushed DC motor up to 10A

continuously by using Raspberry Pi as a controller. It offers several enhancements such as

support for both locked-antiphase and sign-magnitude PWM signal as well as using full solid

state components which result in faster response time and eliminate the wear and tear of the

mechanical relay.

The HAT-MDD10 has been designed with the capabilities and features of:

● Bi-directional control for two brushed DC motor.

● Support motor voltage ranges from 6V to 24V.

● Maximum current up to 10A continuous (without heatsink at 25℃) and 30A peak (10

second).

● Current limiting at 30A.

● 3.3V and 5V logic level input.

● Raspberry Pi compatible connector.

● Manual/test button to fast verification.

● Solid state components provide faster response time and eliminate the wear and tear

of mechanical relay.

● 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).

● Support both locked-antiphase and sign-magnitude PWM operation.

● Support TTL PWM from microcontroller, not PWM from RC receiver.

● Dimension:67.5mm x 59mm
