Motor Control Shield

 

 

 

Motor Control Shield Expansion Board For Arduino with Dual H-bridge Driver L293d

Overview

Motor Control Shield is capable of driving 4 DC motors or 2 stepping motors at one time.

Features

• Configurable motor power supply via onboard jumper
  • when using 5V motor power supply : drives four 5V DC motors at one time
  • when using adjustable motor power supply : drives two 1.25V-6.45V DC motors at one time (9V external power supply is required)
• Onboard dual H-bridge driver L293D x 2
  • each L293D can drive 2 DC motors or 1 stepping motor at one time
  • totally 4 channel H-bridge, with 600mA output current (peak 1.2A) per single bridge
  • ESD protection

What’s on Board

1. External power supply jack
2. Power input/output pinheader
3. Stepping motor interface
4. DC motor interface
5. M_PWR configuration : connects M_PWR (motor power) to 5V or ADJ
6. Power selection switch
7. Power indicator
8. AMS1117-ADJ : onboard linear regulator with adjustable output
9. Adjustable potentiometer : for adjusting the output voltage of ADJ (adjustable motor power)
10. L293D : dual H-bridge driver
11. LM2596-5.0 : onboard linear switching regulator with 5V output

Note : when in operation, it’s normal that the onboard motor drivers and regulators generate lots of heat.
