SCD(Smart Car Daughter) Card

Smart Car Daughter was developed for the two wheels of the car, the infrared sensing, and motor

drive control board. It can be connected to any GPIO Port on the Terasic board. This allows users to

easily control the DC Motor, achieving automatic control purposes. The main functions of the board:

1.

Power System: Buck-Boost DC/DC Converter, 5V/2A output for Control Board Power supply.

2.

Motor Driver: Can drive two Brushless DC Motors.

3.

ADC: 8-channel for IR Sensor input and Battery power meter.

4.

LED: Two white LED for illumination.

5.

Buzzer: You can play some sound.

6.

TMD (Terasic Mini Digital) expansion header: Can use Bluetooth Daughter (

) for the

expansion of remote control.

, the description of the SCD Card hardware architecture and scalable system.
