Operating Instructions:


  1. Attach motor pins to the relevant motor terminal block(s) (see pinout below)
  2. Remove jumpers U2 and U4
  3. Apply 7-46V DC to the VMS pin on the module and connect ground to GND
  4. To enable bridge A (motor A) apply 5V to ENA; to enable bridge B (motor B) apply 5V to ENB

Pinout:



Terminal Blocks
# Name Description
1 A- Motor A-
2 A+ Motor A+
3 VMS Supply voltage
4 GND Ground
5 5V 5V output
6 B- Motor B-
7 B+ Motor B+
6-pin 0.1" male header
# Name Description
1 ENA Bridge A enable
2 IN1 Input 1
3 IN2 Input 2
4 IN3 Input 3
5 IN4 Input 4
6 ENB Bridge B enable


Notes:

  • ENA and ENB enable the H-bridges A and B, respectively
  • Jumpers U1-U4 allow for easily tying IN1-IN4 to 5V.  To allow for full control of the H-Bridges remove these jumpers.  IN1 and IN2 control bridge A; IN3 and IN4, bridge B.  The following example specifies control of bridge A using IN1 and IN2, but the same logic applies using IN3 and IN4 to control bridge B
    • To move the motor forward: IN1=H, IN2=L, ENA=H
    • To move the motor backwards: IN1=L, IN2=H, ENA=H
    • To quickly stop the motor: IN1=L, IN2=L, ENA=H OR IN1=H, IN2=H, ENA=H
    • To slowly stop the motor (free-run stop): ENA=L (IN1 and IN2 ignored)
  • The 5V_EN jumper enables the onboard regulator
  • The CSA and CSB pins are the current sense pins for bridge A and bridge B and can be used to sense the motor current.  These are also broken out to jumpered headers.  If not using current sense leave the pins jumpered to ground
