This is a Waveshare Motor Control Shield. The module is a motor control expansion board of Arduino/NUCLEO. Onboard dual H-bridge driver chip D, allows driving 4 DC motors or 2 stepping motors at one time.

What’s on Board:

1. External power supply jack
2. Power input/output pin header
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

Features:

• Could drive 4 DC motors or 2 stepping motors at one time
• Configurable motor power supply via onboard jumper
• Wen 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 D x 2
• Each D 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
