1.INTRODUCTION
FD04A Rev2.0 is an enhanced version of FD04A rev1.0. It is a motor driver board to control
unit of DC motor up to 2A for each channel. This revision incorporates several important
improvementfromolderFD04A:
FD04ARev2.0comeswithfollowingfeatures:
● Bidirectionalcontrolfor4brushedDCmotor(4Channels).
● Supportmotorvoltageranges:725VDC.
● Maximumcurrentupto1.5Acontinuousperchannel.
● 3.3Vand5Vlogiclevelinput.
● Testswitches(StartandDirection)foreverychannel.
● Motorvoltagepolarityprotection.
● Solidstateswitchforpower.

5Vvoltageregulator
Generates 5V to supply all the transistors and L298P motor driver, include V pin. User can
access 5V (at V pin) and use it to supply another circuit. User is prohibited to supply another
5VatVpin.
7x2IDEsocket
SockettoconnectFD04A.
Extrapad
This is another alternative to access FD04A Rev2.0 control pin instead of using ribbon cable
at7x2IDEsocket.
Reversepolarityprotection
In case user wrongly connect the external power source polarity, this circuit will protect the
boardfrombroken.

Motortestswitch
When button A is pressed, current flows from output A to B and motor will turn CW (or
CCWdependingontheconnection).
When button B is pressed, current flows from output B to A and motor will turn CCW (or
CWdependingontheconnection).

6.4ConnectingtoMicrocontroller
There are two methods to access the control pins of FD04A R2, which are through IDE
connector or extra pads. IDE connector on FD04A R2 is compatible with FD04A. So, for
those already bought the PR19, or build any project that uses FD04A Rev1.0, you still can
replaceitwithFD04AR2.
*Note:5V(Vpin)fromFD04AR2cansupplythePR19mainboard.
